I used a rubber band as my wallet for years and although I loved the slimness, I could not manage more than a month without the rubber bank breaking.
Finally there is a solution. BetaBand is the only rubber band purposed to hold money and credit cards. I spent a lot of time testing different materials and rubber blends in order create the perfect silicone band that actually works to provide a slim, durable alternative to the conventional wallet without breaking from everyday use.
I have used my BetaBand for 3 years now with no chance of ever going back to a regular wallet. It is thin enough to keep in my front pocket, which is safer than the back pocket, and super easy to slip my credit cards in and out.
I hope others get as much benefit from it as I do!
