Lumi-color 6-inch Regular 25 Pink Glow time: Approximately 6-8 hours There were 25 pieces originally, but 22 remain. Stored in a dark place. Expiration date: August 2027 To reduce the thickness, some pieces will be taken out of the bag and sent in an envelope. (Waterproof measures will be taken, but as it is not a box, it will be vulnerable to impact) If you prefer shipping in a box, ① +70 yen (Yu-packet Post Thin Box) Some pieces will be taken out of the bag and sent in a dedicated box to reduce thickness. ② +300 yen (Mercari Rakuraku Mercari Delivery's dedicated box) All pieces will be sent in their original silver bags inside a dedicated box. You can also change to either ① or ②. It seems like cushioning material cannot be added due to the thickness, but shipping in a box may help prevent damage and bending. If you have a preferred shipping method, please comment. I cannot take responsibility for damage during shipping, so please choose carefully. Dai-senko disposable penlight cyalume
