For the model builders and craft enthusiasts out there, this is the Hasegawa TT114 Assorted Model Kit. Now, the description is pretty brief, but it seems the main focus is a craft knife with a triangular-shaped blade.
The knife is specifically designed for model making, which means it's likely meant for precision work like trimming tiny parts, cutting decals, or scoring lines. A triangular blade can be really handy for getting into tight corners or angles that a standard blade might not.
The whole kit weighs about 40 grams, so it's light. \Assorted\ suggests there might be a few different tools or accessories included along with the knife, but the main feature is that specialized craft knife. It's a basic, purpose-built tool for hobbyists who need a sharp, precise blade for working on their scale models or other detailed crafts.
