CPK - Glow In The Dark Pop-Up & Wafters

CPK Glow up pop ups & wafters
Perhaps the most popular product at the moment are the Glow Up pop-ups from CPK.
These pop-ups give light underwater. You simply load the pop-ups & wafters by holding a UV light on them or loading them in sunlight.
The pop-ups & wafters provide good light underwater for up to six hours and are available in garlic, strawberry and pineapple, among others.
So they are normal pop-ups & wafters that give light and not plastic.
