Q: How many cards does it hold?
A: This is up to you. I will ship ready to fit 1 card. You can also add cards and it will stretch, but note once stretched will not shrink back, it’s leather. Just add a second card, and a third between the two if you want more or if you want it looser. It’s like a leather baseball glove, you customize it to what YOU want! Each piece is unique and 2 will never look identical. I have had up to 11 business cards or 4 Credit Cards/IDs.
Q: How well does it stick? Does it fall off?
A: It sticks really well! When I hand mine to people and ask them to peel it off, they are afraid because it is attached so well. It will NOT COME OFF from a simple fall or drop (assuming the back is clean and attached properly) and I have removed several times before I cleaned. The back is not pressure sensitive, can rebond repeatedly, and leaves no residue on the target surface.
Once in place, a 4 in x 1 in piece of the backing is strong enough to hold a 1 lb flat piece of steel. See more here.
Q: What is the micro-suction made of?
A: Acrylic Foam
Q: How long does the stickiness/backing last?
A: The backing will last as long as you want.The bonding time depends how much dust and dirt it accumulates when not attached to something. I have removed several times before I had to clean. But if I was to place it (unattached) in my pocket, I would have to clean from all the lint.
For the REAL technical people / testing results for the micro-suction-
Absorption Force on Stainless Steel at 24 hrs usage 6.08N / 50mm
Absorption Force on Glass at 24 hrs usage 6.37N / 50mm
Repetitive Adsorption Force on Stainless Steel after 240 uses 2.74N / 50mm
Repetitive Adsorption Force on Glass after 240 uses 3.04N / 50mm
Q: What if it doesn’t stick or stop sticking to case/phone?
A: 2 Part answer may help here…
Part 1- Micro-suction (backing) could be dirty. start by using a very small amount of water and rag/paper towel wipe the back/ let dry. Cleaning will rejuvenate the suction to 100%.
Part 2- If that doesn’t fix your issue you may need to *add a piece of wide (clear) packaging tape where you intend to attach the wallet. This will provide a completely non-porous surface for the micro-suction to attach to. This has proven to be a great solve for those rubberized phones and cases.
*Please use tape at your own risk. Test a small area first. I can not be responsible for any damage caused to property from third party adhesives.
