Inkadinkado's unique Inkadinkacling stamps combine the high quality and detail of red rubber with a foam layer and a special cling layer that is more than twice as tacky as standard clings. Flexible, durable, and easy to store, you'll use these with clear acrylic mounting blocks (sold separately) just like clear stamps. Each package includes four small icon stamps, one border stamp, one large icon stamp and one background stamp (seven stamps total) that measure approximately 1.5" x 1.5" to 6" x 6".
