Lava Lamp Mix & Match Decoration Kits (Pack of 8)

What you're getting

You've got 8 different designs to work with here, and the idea's pretty straightforward: pick your foam pieces, stick them onto the templates (they're self-adhesive, so no glue needed), and hang them up with the ribbon that's included. Each kit comes with the foam templates, the decorative foam pieces, and the ribbon to get you going.

It's the sort of thing that keeps kids busy on a rainy afternoon without making a mess of the kitchen table. Peel, stick, hang — done.
