Hello. This is the "Toshiki Masuda Diver Penlight." It's a live merchandise item from March 2020. I've never had a chance to use it after purchasing it, and it has been stored in a dark place. It's a penlight that lights up in 12 colors, and I've confirmed that all colors work. ■Size: W10 x H19cm ■Material: PET-G (light-emitting tube), ABS resin (grip) I also have other Toshiki Masuda related items for sale (photo albums, CDs, bromide photos, etc.)! If you'd like to bundle items with other products, or if you have any other questions, please feel free to comment. ⭕️Instant purchase available⭕️
