Hairclips are made from polymer clay, twice baked.  The metal clip on the back is embedded and baked into the clay and will never come off. The front is sanded with a polished finish. These clips are a labour of love and will last a lifetime. I wont charge for all the hours that went into making them !  They are relatively light and easy to wear - however, this pink marbled hairclip is a little thicker than others I have made so is a little heavier.
