{Duties/Import Taxes}
US citizens!! Did you know that you can import up to $800US worth of our products in one shipment without having to pay customs/duties? If you order more than that we will divide your shipment so that each parcel is less than $800US.

Residents of all other countries:
Use this calculator to get an estimate of the amount of duties you'll be charged when the parcel is imported into your country - https://www.simplyduty.com/import-calculator/
Enter 3924.1 as the HS Code.

--------------------------------------------------------------

{Important}
• Do NOT use a torch with this mold! Doing so will damage the surface of the mold and can cause your resin to permanently fuse with the silicone.
• Our molds are not suitable for use with a pressure pot.
• Slow curing or harsh resins may cause your molds to wear out faster and/or lose their transparency/turn white.
Please note that I will not replace molds that have turned white due to the resin used.
Feel free to contact me for information on resins I recommend/don’t recommend.
