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 various colors. The vials measure 1.5mm x 6mm and are made with real Tritium. Charging in light is NOT required for a strong glow. When you purchase one of these glow-y sets, you will also receive a free sticker! Duh....
