Hello. I’d like to share a little about the current progress on the development of the new slim mini wallet, the “Tenuis Mini,” which I mentioned last time. My mind is already starting to feel as stiff as the waxed canvas in the photo below, and it’s in the midst of trying to flatten out.

What I’m envisioning right now is a minimalist size of approximately “less than 90 mm in height and in the low 80s in width” when folded in half. To keep it within these dimensions, the layout of the “cards” and “coins” becomes the key challenge.
However, there’s one major hurdle here. If we try to directly apply the “coin-and-card non-overlapping structure”—which is already common in the market, and in SOLAHANPU’s case, the structure of the “TYND”—it actually makes it harder to make the wallet this small, so we need to come up with a different structure.
Right now, we’re in the thick of trial and error regarding the direction of this structure. Various ideas keep popping into my head and then fading away, over and over again. But I’m taking on this challenge driven solely by the desire to deliver a structure that balances beauty and functionality—one truly worthy of being a “mini version of Tenuis.”
To be realistic, since the overall surface area will be smaller than that of the standard Tenuis, maintaining the same thickness will likely result in a naturally reduced maximum storage capacity as a wallet.
But I also believe that’s precisely why we’re able to achieve this mini design. Will it be the standard version that holds a lot, or the mini version stripped down to the bare essentials? It may come down to each user choosing based on their personal style and how much they typically carry.
Well, since various aspects are still in development, there isn’t much I can share in concrete terms just yet… But I wrote this blog post because I wanted to share these development challenges with all of you who always support SOLAHANPU.
How will we overcome this challenge? Please stay tuned for future updates.
