20oz Skinny Tumbler Sleeve - 3D Printed Blank Sleeve for Customization Drinkware Clay Thin

•Long and excessive heat can melt the sleeve material due to this being plastic. Using lots of heat will turn the sleeve soft which will alter the shape of the sleeve. Do not leave your tumbler sleeve in any hot environments such as a hot car or in the sun for long periods of time.  

•Do not use long and excessive heat from a torch or heat gun as it may melt the sleeve material and go soft which will alter the shape of the sleeve.

•Do not bake your sleeve. Polymer clay can only be added after they are baked. Other sculpting materials can be used to sculpt directly on to your sleeve this includes:  Air dry clay

•We strongly recommend adhering your tumbler into your sleeve with a very strong glue or epoxy. 

•Due to the fixed dimensions of the sleeve it is not recommended to add more than a thin layer of epoxy or glue to the tumbler when adding the sleeve. The sleeve will only properly work on a blank tumbler, adding additional materials before adding the sleeve such as an ink drop tumbler or glittered tumbler prior to adding the sleeve may result in the sleeve not fitting over the tumbler. Please take this into consideration.

•Our tumbler sleeves have a lined texture from manufacturing. To minimise this it is recommended to coat your sleeve with a thin layer of epoxy or an epoxy alternative. 

•Tumbler sleeves are not waterproof and should always be sealed for protection and durability with an FDA compliant epoxy.

•Some minor imperfections from manufacturing may occur.
