These boxes are well made and sturdy to hold 2x2 coin flips. I have used these boxes for many years and they have held up through the years.

These boxes (4 of them) are exactly what I was looking for. To my surprise they also came with 100 ct of penny flips (in each). Great bonus except I also bought 200 ct of penny flips with this order. It's all good. These boxes will keep all my flips in order.
