Phone Card Holder’s that Last – How they are Made

How do you make the best Stick on Phone Card Holder that lasts for years?

First you must think of where would a phone card holder fail.

  1. Wallets can break apart in the stitches between the leather pieces
  2. Wallets can fall off a Cell Phone after they are stuck on
  3. Wallets can stretch too much and no longer hold cards

Did you know? : Sticky double-sided adhesive tapes expire in ~5 years if not used, so we ensure that all tape is brand new. This means if you buy a very old sticky item they usually don’t stick very well!

Final Goal Product:

This blog post is meant to explain how we got such good reviews for durability and what sets Wallaroo apart!

#1 Stitches

In order to make the stitches last for a very long time we must stitch the wallet toward’s the center; Instead of near the edge.

The Blue Arrow shows the few MM gap between the edges. The edges which are then sealed with a Wax-like epoxy to add strength. This ensures their is minimal edge tear.

If you have stitches right on the edge of the wallet we have found that the wallet ends up breaking apart, and won’t last more than a month. Using this improved process of stitching towards the center we see years of wear, but added material cost because you must buy more Genuine Leather in order to still fit a Credit Card while having a few MM of space between the stitching and the edge.

#2 Falling Off

We use premium 3M adhesive. While some wallet makers save money by getting off-brand or less sticky adhesive; we know that its the only thing keeping your wallet stuck on and our goal is for every wallet to out last the cell phone.

Little Known Fact:  Most Transfer Tape Adhesives are at their maximum strength ~24 hours after being stuck on the the cell phone. That means you should wait 24 hours if you want maximum strength, but within a few minutes it’s usually 70-80% of its Strength after being stuck on the phone.

#3 Stretching

Initially our tests show we had a stretching issue, but we solved it by adding a line of stitching on the top of the wallet.

This stitching cross-over added enough stretch, while still allowing it to go back to its initial form.

You can see the ends are capped in an Wax-Like epoxy and cut to size as a final measure to ensure no loose threads.

Note: Different Thread & Stitching types have different abilities to stretch, depending on which ones you buy they may be more or less elastic!
