This flexible mould is made from 100% platinum silicone and needs no mould release, making it ideal for all your resin jewellery creations. It has 15 different button designs (& 21 cavities - smaller button shapes are in pairs), all have 2 or 4 prongs so that the castings can be used as actual buttons. It is 13x18.5cm in size and the cavities range from 15 - 30mm approximately. They can also withstand high temperatures (446º F / 230º C ) so can also be used with polymer clays.
