This is a penlight from Sutopuri (StrawberryPrince). As it's the first Sutopuri penlight, I believe it has high value. It's the penlight from Strawberry Memory Ver. 3. I used it a few times at live concerts after purchasing it, and have stored it in a dark place for several years. I lost the original strap a few years ago, so I've attached a different strap. Available for immediate purchase.
