These pretty 1/2-inch (13mm or 20L) buttons are made of pure corozo nut, the smooth, hard seed of the Tagua palm, which grow naturally in the wild and can be sustainably harvested without harming the trees or the rainforest habitat. These simple two-hole buttons are a perfect fit for cardigans, shirts, and anywhere else you'd like a button. Pick from 17 colors, created with plant-based dyed to match some of our most popular yarn colors! Each button is sold separately, and they are also available in small and large sizes.
