★ Measurement: approx. 3mm, 4mm, 6mm, 7mm and 9mm (W)

★ Can be washed with hot, soapy water. But do not wash mold with abrasive pads or cleaning agents.

★ Tips on clay: If you use it on clay, since some clay are sticky and softer than the others and so affect the pop out effect, in this case, we recommend you to put the mold (with the clay inside) into the fridge for around 5-10 minutes before you pop the clay out.
