This is Glass luminous tube, not Trils. it can be recharged by any light source with high glow, the best glow bar instead of Tril vials.
Inside is uses Rare earth glow elements, outside uses Transparent glass material, makes it to achieve the effect of trils. And looks same as Trils.
It can be recharged by any light source, we recommend using UV light, flashlight, Sunshine, also can be use phone, table lamp etc. Just shine it less than 3 mins, and can be last more than 3 hours. Highly recommend!
