Do you remember Chunky Books? They were a swap fad a few years ago, and I always liked that 4" square page size... hence these new chunky blanks (rounded-corner 4" squares).
The same thick grey chipboard as the large 3D shrines, these coasters can take a lot of embellishing!
(Hint: there are a few Alice Collage Sheets that include 4x4 images.)
One of the extra photos above shows two of these coasters inside a 4.5 Inch Dimensional Coaster Folder (one of a big bunch of “holders” (pockets/wallets/folders) designed to fit the Art Coins or Coasters announced with the Coins, Coasters & Holders Kit).
Another photo shows one of these coasters with the smaller 2.5 Inch Trading Coasters.
