These Moulds are made from Low Density Polyethylene (LDPE).

The advantages to LDPE are:

Robustness to Chemicals- High oil, fragrance, or PH content is no issue.

Flexible yet sturdy- Hold shape well, but press out easily.

Regain Original Shape- Go back to their original Shape once un-moulded.

Semi Clear- Able to see your creations in action!

FDA Approved- Suitable for creating food safe products.

Withstands temperatures as low as -50, and +80 (Celsius).

Multipurpose- Can be used for Bath Bombs, Waxes, Body Bars, Chocolate, Sweets, Soaps and More!


We suggest washing well before use in warm water with a drop of washing up liquid, patting dry, and allowing to air before use or storing.

In addition, the Manufacturer of the plastic recommends storing away from UV lights, and not to use anything abrasive  which could scratch the surface of the mould. Abrasive materials can make the mould weaker, or more difficult to unmould your projects.

(Please be aware, that due to the processes involved, occasionally you may find a wrinkle, or crease on the flat part of the plastic. All items undergo checks to ensure that it will not effect the use of the mould, and are therefore nothing to worry about).
