I can't recall but according to an entry at Amazon: https://preview.tinyurl.com/y7javwrt
American Crafts Bazzill Basics Self Adhesive 2mm Foam Sheets, 12" x 12", Black
by American Crafts
describes it as:
Product description
"These self-adhesive foam sheets are the perfect addition to your scrapbooking or paper crafting project. This 12 x 12 inch sheet comes in a design with adhesive backing is perfect for any project of yours."
Hope that might help. Bazzil's site probably has a more definitive description but Amazon popped up first in my search results.
