Ni Glo is a glow in the dark keychain perfect for marking SCUBA tanks and outdoor gear. Like a reusable mini glow stick, this gear marker is rechargeable and makes a useful camping accessory. Simply attach it to keys, backpacks, fishing rods or tents and watch it glow bright green for two hours. It then fades to a constant glow that lasts throughout the night. To recharge, expose it directly to sunlight or indoor light. For best results, charge under the sun for two hours. Small and lightweight, it’s a convenient marker for trails and dive sites. Whatever outdoor activity you’re into, Ni Glo will mark the way.
