Designed to fit all WYFFR caps, the replacement button seals glow in the dark and can be changed very easily. The seal of the WYFFR is made of glow in the dark rubber making it easy for you to find your bottle when all lights are off.
For best results, charge the seal under the brightest light or a strong lamp for a few minutes before setting the mood. The seal helps providing an extra layer of protection but is not 100% leak-proof.
If you need replacement seals, this is the pack for you.
