Make stupendously chunky keyrings with these fab 40mm Number Moulds -  use a Dremel tool to drill a hole in the top of your new resin piece, thread in an eyelet and attach a keyring - it's super easy to do. We think transparent tints and a bit of aurora dazzle will never fail to make some funky pieces!

  • Each number made is approx 40mm high, 28mm wide and 8mm deep (obviously except for number 1, being 20mm wide)
  • Comes in a bag including 10 moulds, all numbers 0-9
  • Each symbol takes approx 10ml of resin or 20g of JESMONITE to fill

As these moulds are in reverse, we suggest either adding texture to the top (in the form of our glorious mica flakes), or sanding back the top surface (using our Rejuven8 polishing collection), or if you don't have the time simply add a doming layer (using coat-it) a further 8-10 hours after the second layer.

How to look after your new mould: top tips from the Resin8 team

Our silicone moulds can be used multiple times - to get the very best resin results it is important to care for them perfectly. Keep your mould in the bag it comes to you in and store carefully moulds do not like to be stacked or kept contained in a box with other items, this will result in the mould losing its shape. Moulds that are more complex to demould from will not last as long as straightforward, plain moulds.

It is best to use a heat tool such as an embossing craft gun to rid bubbles from your creations, naked flames can damage the outer edges of your mould. Take extra care when de-moulding your creation, pay special attention to not scratch the interior of your mould with long fingernails.

Any residue left in your mould once you have finished using it can be brushed out with a soft bristled brush such as a watercolour paint brush. Do not use sticky tape to de-tack dust, fluff or glitters - doing this will remove the interior shine within your mould.

If your casting comes out dull it could be that the mould has come to the end of its life (or that the mould doesn't have a shiny interior surface). You can keep using moulds that are past their best - it just takes a little more effort. Add a thin layer of resin to the casting or use polish and a cloth to bring up the shine. 

You might like to consider using moulds that have past their best for another exciting craft. How about exploring the wonderful world of JESMONITE? Resin-tired moulds make excellent moulds for working with JESMONITE​​​​​​​.  You can find more about this wonderful composite here.
