Unicorn diamond art coaster set

My 6 year old does diamond art. She is trying to make money to buy a 10X10 frame for her latest diamond art painting. This was a set of 8 but one received damage when a piece of paper was accidentally put over it before the diamonds were placed. So, it's a set of 7. These are sealed so they won't fall apart and have a thin corkboard on the back to prevent sliding. Metal rack included.
