It is just construction paper and I put tape on the back of the airtite, roll the tape around to stick it to itself, to stick it to the paper and the glass kind of pushes against the airtites too. That means yes, they do come in every size because you just cut the paper to the size backer you need.

Pretty quick and easy!

The hardest part is finding frames that are deep enough to hold the chips, without having to get the really deep shadow boxes or display cases. These small frames just happenned to be on sale for $5 each and are the perfect size for the thickness of chips.
