These are a charged UV glow in the dark tumbler. That means it needs to sit in U.V. light (i.e. the sun) for a bit before it will glow brightly in the dark.

These do not have a logo of any brand on them.

Hand wash only with a light soap.

Please feel free to ask any questions before purchasing. I do accept custom orders, so please reach out to me before ordering.


Due to high volumes of orders, I can only send mock ups of items that I have pictures of.

I cannot send pictures of cups before they are sent out.
