Safe-T Flips flips are very easy to use, just insert a coin and fold over. Each flip is made with a double pocket design. One of the pockets can be used to hold the coin, while the other can be used to hold information about the coin. These information sheets are called inserts, all of our Safe-T flips have inserts included. We are proud to offer these flips in multiple sizes. This range in size allows customers to choose the right flips for the right job.
