These rings, made of transparent plastic, are ideal for hanging light curtains and for various handicrafts. Its transparent look ensures that the plastic rings can be universally used for any material and for any curtain rod. They are available in Prym's assortment with an inner diameter of 11 mm and an outer diameter of 16 mm. These rings cannot be opened and must therefore be directly sewn onto the curtain with a fabric loop. The card contains 30 plastic rings.
