As delicate and light as a fruit tree in full bloom, this button is the perfect finish for a handmade bracelet. We have used it in multiple projects, including Stackable Ladder Bracelets and the Odyssey Bracelet, and it seems to work every time. The shank on the back will easily accommodate up to 2mm Leather and most of our Deerskin Lace if you angle cut the end. Other fun projects using buttons for clasps can be seen on our YouTube Page. Enjoy! Made in America by TierraCast® of metal both lead and nickel-free. It is considered hypo-allergenic.
