The Foam Adhesive 11 pc Pack is part of the Chibitronics Collection from We R Makers. The foam tape can be used inside the Chibitronics crafting products to keep everything in place and to keep spaces between the two layers of your projects. 

This kit includes five battery holders, five foam battery holders, and one 1.5 meters roll of double sided adhesive foam tape. This kit will help you hold your batteries in place when using the lights on your projects.

The foam pieces can be cut to fit around the lithium batteries (sold separately).  This kit can help you make cards, scrapbook pages, tags, journals, and other paper crafting projects that you want to add lights to.
