2026 BulletTrain SAFE Wallet ULTRA

I finally got a chance to experiment with and photograph our first BulletTrain SAFE Wallet ULTRA prototype which is pictured below next to our BulletTrain 2017 SAFE Wallet MINI which has a Magsafe backplate attached to it for prototype testing, so I thought I would share this picture. The reason why the ULTRA is salt and pepper colored is that's the a limitation of 3D printing process, but the production model will look almost identical to the MINI at it will be black.

It's fascinating to me to observe how remarkably similar the two models are, yet totally different. 

-The MINI is made from polycarbonate and the ULTRA will be made from TPU.

-The MINI holds 5 cards, yet the ULTRA holds 5 cards.

-The MINI attaches using Microsuciton, and the ULTRA attaches using Magsafe magnets.

The whole process of getting to market is taking way longer than I would like, but as they say, good things take time. There is some pretty miraculous engineering going on to bring this beauty to life. In particular, the level of detail that goes into the magnets makes my head spin, but that's part of the magic as everybody will soon see.

BulletTrain SAFE WALLET ULTRA: Magsafe Prototype #1

Magsafe Prototype #1

Below are photos of the first 3D printed prototypes of the SAFE WALLET ULTRA Production Prototype model, and it kind of throws me off to see it with the Salt and Pepper colors, but the geometry is AMAZING, and so far it's looking pretty good for a first 3D printed prototype. The next step is to test these prototypes, then probably make a much more advanced prototype, before we start making the tooling, and go into production. I've patiently waited a decade and a half for this singularity to occur, and I could not be more excited!!!!

Just to be clear, all the photos of the black BulletTrain SAFE Wallet prototype on the BulletBlog use our BulletTrain SAFE Wallet MINI with a MagSafe backplate. The prototype in this story is of the actual BulletTrain SAFE Wallet ULTRA, and is NOT in any way based upon our MINI. The two models are remarkably similar, but the key differences are:

-ULTRA will be made out of TPU (MINI is made from Polycarbonate).

-ULTRA has a much deeper ID Tray (MINI has a Cash Stash, that is much shallower.

-ULTRA holds 6 plastic cards internally. 1 card in the ID tray area, and 5 in the hollow core door, along with a cash bill. (MINI only holds 5 cards in hollow core wallet door, and up to 2 cash bills in Cash Stash Area.
