On top, instead of a traditional stem, i added a little wizard owl (the kind you in fairy gardens) - the cutest little thing and not at all scary. The size of this pumpkin is 5 inches in diameter and 4.5 inches high including stem (meaning owl). Inside is a solid plastic pumpkin, and the grout is professional tile grout.Like all my pieces it is handmade in my studio in san carlos, ca. It can be used inside as well as outside in dry conditions. If you have any questions please never hesitate to contact me. Thank you for shopping handmade. This item is made of black pebbles and plastic pumpkin, resin owl.
