These are nostalgic, large drafting triangles (set of 2). They are sturdy, vintage, Japanese-made items with a "Made in Tokyo" stamp. Being a large 30cm size, they are useful not only for drafting, but also for DIY, drawing lines on patterns, and cutting work. Suitable for architectural exams! (Actually used in practice) ■ Product Contents ・ 2 triangular rulers (45 degrees, 60 degrees/30 degrees) ・ Dedicated vinyl case ■ Brand/Marking SMZ / Drawing TRIANGLES / High Quality Made in Tokyo ■ Size Nominal size: 30cm (Not a size that fits in a typical pencil case; these are large drafting tools) ■ Condition As these are old items, there are fine scratches and signs of use on the rulers themselves. Also, the included vinyl case shows wrinkles and discoloration due to aging. There are no cracks or chips, and they are perfectly usable, but please understand that these are retro, used items before purchasing. ■ Shipping Method They will be reinforced with thick paper or cardboard to prevent bending, and placed in a waterproof vinyl bag before shipping. How about using them for architecture, design, handmade crafts, etc.? Thank you for looking. #TriangularRuler #Drafting #Architecture #DIY #ShowaRetro #Vintage #Ruler #SMZ #AntiqueTools
