The GUNPLA-KUN DX SET is a Gunpla kit with recreational parts, offering a fun building experience for ages 8 and up. - Model Name: GUNPLA-KUN DX SET - Accessories: RUNNER (Recreational Parts) - Manufacturer: BANDAI - Target Age: 8 years and older Although listed as new and unused, the box has been opened once. I purchased it at a 7-Eleven about 2 to 3 years ago. I really liked it at the time and impulsively bought it, but when I tried to build it, I didn't understand how. (Late 40s, zero plastic model experience) A male colleague at work told me, "It's easy, so even a beginner can do it if they try," but I still haven't touched it. I don't think I'll ever take it out of the box. If anyone is interested, please consider it. Thank you.
