Glowing is knowing....HOW COOL YOU ARE!!! These vials are sold in pairs and will fit the Slotted Manix 2 Ball cages. Adhesive is not included in this kit. The pairs come in a choice of eight colors: red, purple, blue, pink, teal, orange, white, and green. The vials measure 1.5mm x 6mm and are made with rare earth minerals. Charging in light is required for a strong glow. When you purchase one of these glow-y sets, you will also receive a free sticker! Duh....
