Your storage, your way.

Stop searching through scattered supplies. Your routine deserves a setup that’s considered, organized, and ready when you are.

Flex Vault gives your syringes, vials, swabs, and overflow supplies a dedicated home in precision-machined aluminum. One completely open cavity gives you the freedom to organize your way, with no fixed compartments or predetermined layout. Made in Texas, USA, with craftsmanship you can see and feel every time you pick it up.

Choose Mega, Mini, or Micro in Raw Machined or Anodized Black. Select With lid for a standalone organizer that can also join your stack, or Lidless to add storage beneath a compatible same-size lidded vault. One complete system, one footprint, organized around your routine.

Compare sizes & capacity

Three sizes. The same attention to your routine. Choose the space you need for the supplies you actually use.

Mega

Room for a full setup and a growing routine, in a footprint close to a tablet or cigar box.

  • Exterior: 8.5" L × 6" W × 1.75" H.
  • Interior cavity: 8.10" L × 5.55" W × 1.34" deep.
  • Weight: 2.52 lb with lid; 1.67 lb lidless.

Mini

For a simpler routine. Space for the supplies you reach for every day, without the larger footprint.

  • Exterior: 6" L × 5" W × 1.75" H.
  • Interior cavity: 5.75" L × 4.63" W × 1.34" deep.
  • Weight: 1.49 lb with lid; 1.02 lb lidless.

Micro

Your routine comes with you. The same craftsmanship in our smallest footprint, with open storage for the essentials you want close at hand.

  • Exterior: 6" L × 3" W × 1.75" H.
  • Interior cavity: 5.75" L × 2.63" W × 1.34" deep.
  • Weight: 1.01 lb with lid; 0.69 lb lidless.

Each size has one open compartment. Capacity depends on the dimensions of your supplies and how you arrange them. All three sizes are available in Anodized Black and Raw Machined. Choose With lid or Lidless in either finish.

Materials & finishes

Pick it up and feel the difference. Every Flex Vault is precision-machined from billet 6061 aviation-grade aluminum, giving it the substantial feel and carefully finished interior that make this part of your routine worth looking forward to.

The open cavity takes longer to machine than a standard vault, and its interior is finished with the same care as the outside. The result is a statement piece as much as a tool, whether it sits on your counter, on a shelf, or in your refrigerator. Designed, machined, and assembled in the USA.

N52 neodymium magnets draw the removable lid into place. When you’re ready to access your supplies, lift it off and store it flat underneath the vault. Choose With lid for a matching lid, or Lidless to stack beneath a compatible lidded vault in the same footprint.

Raw Machined

For those who appreciate seeing how something was made. Visible tool marks and the natural sheen of aluminum give Raw Machined its industrial character. Subtle surface variations make each vault its own, and the finish develops more character with use.

Anodized Black

A deep black finish with a clean, understated presence. Type 2 anodizing treats the aluminum surface to resist scratches, oxidation, and wear, giving you a finish made for regular use. Choose Anodized Black for a sleek look that lets the shape and machining speak for themselves.

Will my vials fit?

Flex Vault gives you one open cavity to arrange your supplies your way. There are no fixed vial slots, so fit depends on your items’ dimensions and the layout you choose.

Room for the supplies you use

  • Syringes and needles.
  • Bacteriostatic water and reconstitution supplies.
  • Alcohol swabs and gauze.
  • Extra vials, pill vials, pill bottles, and other overflow supplies.

The organizer is suitable for refrigerator or counter use.

Check your measurements

Before ordering, measure your vials with the caps on and check your other supplies in the position you plan to store them. Compare their dimensions with the interior cavity measurements in Compare sizes & capacity above. The mL label alone does not confirm fit.

All three sizes have an interior depth of 1.34 inches. Allow room for the lid, or the base of the vault above, to sit flat when your supplies are inside.

Not sure about your supplies? Contact us with their measurements before ordering. We’ll help you find the right vault for your routine.

How stacking works

Match your size

Pair Mega with Mega, Mini with Mini, and Micro with Micro. Matching the footprint lets the vaults and their magnets line up correctly.

Choose your lid option

With lid gives you a complete organizer to use on its own or as part of your stack, with its own removable magnetic lid. Use it solo for whatever your routine calls for, or stack it with a compatible same-size vault above or below.

Choose Lidless to add open storage beneath a compatible same-size lidded vault. The vault above covers the Flex compartment, so you gain room for your supplies without an extra lid to manage.

Make room for extras

Place a lidless Flex Vault beneath your matching TRT Vault. The TRT Vault’s base covers the Flex compartment, and your lid stays on top of the TRT Vault. Your primary supplies above, your extras underneath, all in one setup.

A lidless Flex Vault also pairs beneath a same-size lidded Peptide Vault. Keep syringes, bacteriostatic water, and reconstitution supplies organized directly below your vials, bringing your vial and supply storage together in one footprint.

What’s included

Your vault

One precision-machined aluminum Flex Vault in your selected size and finish.

Your lid option

  • With lid: One matching removable magnetic lid.
  • Lidless: No lid included. Designed to sit beneath a compatible same-size lidded vault.

Make it your own

Fill your vault with your own vials, syringes, alcohol swabs, and other routine essentials. Supplies and any additional vaults shown in photos are not included.

FLEX VAULT MINI LIDLESS - Anodized Black | Shop Seconds

This review is showing under the Flex Vault Mini Lidless Anodized black but will cover all three items I have purchased.
First item I purchased was the TRT Mini Vault Anodized Black. I order it from their seconds stock looking to save a little money as this is the first item I have purchased from them. When I received it what I noticed first was that the packaging was very well done. The item was in its own box, in its own plastic bag. Bubble wrap around the item box in the shipping box. It came with the receipt with a personalized thank you note written on it. Looking over the item, you can see that the build quality and coating were don’t to perfection. This item being from their seconds inventory I expected to see some noticeable defects. I did not, the item looked perfect to me. There is one slight imperfection on the coating on the top but you have to be looking to even notice it. I liked this vault so much I looked at other items that they sell. The second item I purchased was the Vitamin Vault Mini Anodized Black with lid to go with the TRT vault. I again purchased from their seconds stock. Again, the build quality and coating were don’t to perfection. I could not see any imperfections on this item. Packaging aging was perfect with another personalized note thanking me for my second purchase and continued support. Well I decided to see what else I could add to my stack to further enhance it. The third item was the Flex Vault Mini Anodized Black without a lid. I again purchased from their seconds stock. I got this item without the lid because I am stacking the TRT Vault on top of it. And again, the build quality and coating were don’t to perfection. I could not see any imperfections on this item either. Packaging aging was perfect with another personalized note welcoming me back and thanking me for my third purchase and continued support. One final note, the time from purchase, to shipping, to receiving the item, was very quick. Faster than I had expected and they notify you along the order and shipping process so you know what is going on. I highly recommended this company to anyone looking for items like these. All American made in the USA. Thank You TRT VAULT you guys are that best!!!!

Perfect and functional.

Closed raw aluminum TRT Vault beneath a CNC cutting tool, surrounded by metal shavings.

It started with a routine like yours. 

Mitch wanted a better way to organize his own TRT supplies. Drawing on his background machining racecar parts, he created an aluminum organizer built around his routine. That became the first TRT Vault.
