These handmade glass toggle clasps are truly one-of-a-kind creations. Made from borosilicate glass, they are incredibly strong and durable. These clasps are so stunning you will want to make them the focal point of your necklace, and we strongly recommend doing just that! These toggles (both loop and bar) vary in size and color pattern. Being handmade, some of the colors will be more saturated and some of the sizes will vary, making each one unique!
