Order and save on the Sizzix Under the Sea Thinlits Dies by Olivia Rose (5 pack) online at CraftDirect.com. Thinlits are wafer-thin dies that will work with almost any machine, and you can use them for multiple purposes: cut, stencil, and emboss. To emboss, you need a silicone rubber sheet and an Impressions pad, both sold separately. Make your under water theme possible with this fun-shaped die set!
