These buttons are made with pigments that change color with temperature shifts! They're also loaded with fun sparkly things, too.
They're pictured here at various stages of toastiness.
Each set of buttons contains six (6) buttons. Buttons are 3/4" (19 mm) in diameter and made of resin and a whole bunch of sparkly stuff. They can be machine washed and dried on gentle cycles (or by hand!) They have two holes and can be sewn onto items with regular needle and thread.
Pease note: since these are handmade, they may have variations in shiny stuff distribution and color. I make them as one "lot" but you know, handmade. It's recommended that you buy what you need for your project since each run is a one of a kind.
