I purchased this handmade item made of resin. The red, glittery eyeballs are a bit horror-themed, so how about using them as part of a Halloween costume or cosplay? They're hairpins, so they're not too flashy, and I think they'd be within the rules for children attending school. Approximately 5.5 centimeters long. Please understand that there are some rough patches and air bubbles on the surface, dirt on the back, and possibly very minor rust on the metal part of the pin. I have worn them before, but I have no hair-related illnesses or anything of the sort.
