- Does it work with UV resin as well as epoxy?
- Yes. The cavities suit both UV resin, which cures under a lamp, and two-part epoxy. UV resin lets you demold faster; epoxy needs its full cure time.
- How big are the finished letters?
- Most letters are about 39–40mm tall and 32–44mm wide, with 8mm depth. The narrow ones, like I and 1, are only about 11–12mm wide.
- Can I use it for keychains and pendants?
- Yes. The 8mm depth gives a solid piece you can drill or set an eye pin into for keychains, bag tags and necklaces. Add a hole before curing if you want a cleaner finish.
- How do I release the resin without breaking it?
- Flex the silicone and push from the back once fully cured. A light coat of mold release helps with epoxy, and warm soapy water cleans residue between pours.
- What temperature can the mold take?
- The stated range is -20°C to 200°C. That covers normal casting and warm pours, but keep direct heat and open flame away from the silicone.
- Is it one mold or a set?
- It is one sheet containing all 26 letters and 10 digits. Each cavity is separate, so you cast one character per cavity per pour.
