This Super Mario ornament glows in the dark after being exposed to light. All artwork is done on the inside of the bulb. (up to 4 different pictures around ornament) Our ornaments are glass and measure approximately 2-5/8 inches in diameter. Tops/lids will be either gold or silver depending on what I can find at the time. Re-purposed materials used to make each ornament (see last image). Each ornament is handcrafted by us and made to order. (possibly 1-2 days extra during our busy season: October, November, and December). If you do not see a design that you want, please send us a message!
