I purchased four color-changing gradient lights from DAISO: three white and one black. I have stored them in a dark place since purchase. They have been stored for a while, and I haven't tested them to avoid breaking the seal. Please be aware of this. Packaging: The items will be placed in an OPP bag, then bubble wrap, then another OPP bag, and finally an envelope.
