The flips are great BUT......The plastic containers that the holders are in come apart too easily and do not keep a tight seal. This causes the adhesive to adhere to the film layer over the adhesive. Most of my flips ended up sticking together. If you aren't going to use these all at one you might consider an alternative. This means I will have to find another supplier.

The alignment precision was excellent, but the 50-cent holders did not do the intended function, that being self adhesion. After placing 50-cent coins into several holders and pressing the two sides together, within an hour the sides began to separate. The coins were not held snugly at that point, allowing them to slip and possibly fall out.

What a wonderful product! Very easy to use and keeps the air and moisture away from the coin! I love them!

I recently purchased some SUPERSAFE COINHOLDERS that were defective when I contacted the store they were more than happy to replace them within four days. also the person I spoke to was very friendly and polite. I have always found their prices low and fast delivery.
