Accordion Minis are THE VERY BEST grandparent gift hands down. My mom carries hers with her everywhere and is the first thing she pulls out when talking about the kiddos. They are small and stylish, allowing you to put it in your purse and carry it with you wherever you go. My husband even had one he carried around with him when he was traveling constantly. They are customized with up to ten of your photos and have a handy magnetic closure, preventing damage while at the bottom of your bag.
These are a great value and a definite must have on my gift list for the grandparents for every major holiday!!
