6 Bernina 1630 Memory Keys-Blanks/Saves

This is a group lot of 6 genuine Bernina, made in Switzerland, memory keys for the model 1630 Inspiration Plus sewing machine. These are the “memory” labeled ones which means you can save what you want on them, and since they are used, they may already have some saved stitches on them–I just don’t know. Have fun finding out what is on here! I believe they can be written over with new information if desired like most memory devices, but I am not familiar to know for certain. Smoke-free/pet-free.
