This is the SLIDER from Hanayama's "Huzzle" series, a stylish and chic puzzle. It has no killing power and cannot be used as a weapon. I bought this thinking it was a cool bottle opener, but it turned out to be a puzzle. I apologize to anyone who opened this page thinking it was a cool bottle opener. Actually, I'm really sorry if you opened this page thinking it was a cool bottle opener. I apologize for leading you all to the wrong place. Yui Hirasawa. It consists of three parts: two sliding pieces and a circular disc in the middle. By skillfully adjusting and pulling, you can take it apart. I succeeded once, but I was afraid of losing it, so I put it back together. I don't care what happens now. After all, I forgot how to take it apart. The box and instructions are not included, only the main body. It seems like I played with it quite a bit, as there are fine scratches and soot stains in various places. Please consider purchasing this as a toy to simply enjoy taking apart and putting back together. Eriko is at 4. I think it's difficult to understand the size, so I've prepared a comparison image with a very common mascot keyholder that can be found in any household in the fourth photo. Please note that this is not the product. I think I picked up the Hanayama "Huzzle" series before, saying it was cool even though I didn't know what it was. I think the previous one I mistook for a device that fires Master Spark. The stylish design, which is unlike the usual puzzle, and the slightly unconventional way of taking it apart are interesting features of this series. This one was a relatively standard "adjust the position and move" type, but I'm frustrated that I actually enjoyed it...! Bikin Bikin. Sensitivity 3000x Bikini Kibit ('◆')
