Hand Made Silicone Rubber Mould for Rainbow Trinket Tray

This mould makes a 15x8x1.5 cm tray. 

The depth of the mould allows you to control the depth of your final product. 


Made with Polycraft General Purpose Mould Making Silicone Rubber - Medium Hardness that is durable, flexible and allows easy de-moulding.

Please note, I only work with jesmonite and never tried this kind of mould with resin, plaster or concrete before. 


There are some small surface imperfections but these are not effecting the casting result.

Each mould is made by hand and tested out with Jesmonite to make sure it gives the best result possible. 


Hand made with love in the UK.


Please note:


All my moulds are hand crafted by me and not a mass produced by a factory. From its hand made nature minor imperfections might occure in the process of making these moulds.


Postage fee not included. Please check out my Shipping Policy for postage fees.

This mould is made with non-food grade silicone. 

Tray is sold separately.

Results depend on the appropriate mixing and casting method used for casting.
