Itsy Bottles are available in two styles; Itsy Bottle Channel and Itsy Bottle Plain. The Itsy Bottle Channel has a recessed area that can be left just as it is, or it can be filled with epoxy clay and embedded with Rhinestone Chain, Ball Chain, Bead Caps and more. The possibilities are endless of the fun that can be created with these! The tops of the Itsy Bottles are cast in the USA from Lead-Free Pewter and plated copper, 24k gold and .999 silver. The Itsy bottles are glass. The Itsy Bottle tops and the glass are unassembled and need to be glued to assemble once filled.
