Make your Potionz glow! Potionz Stick-On LED Coasters are great for parties, board game nights, or whenever you want to make your drink magical. 
 
Using dry hands and a dry Potionz bottle, remove the white adhesive cover of the coaster and gently but firmly attach the sticky backing to the bottom of your Potionz bottle. Click the center of the coaster to turn it on/off. 
 
Works best when the bottle is filled with plain water or Potionz Drink Mixes and Potionz Magic Dust.
 
Be sure to dry the bottom of your bottle before applying the coaster as water/condensation will reduce adhesive strength.
