#Class 1 Architect #Class 2 Architect Protractor Triangle ruler This is a 15cm mini protractor. I bought it on Amazon. List price: 2400 yen I am selling it because I passed the exam. Compared to the larger size, it is much easier to handle and helped me save time and reduce errors, especially in drawing interior walls, which I found difficult. It is designed specifically for the architect's drawing exam! It can be used smoothly for drawing escape routes and columns! The template has a moderate thickness, so the lead does not break easily. I bought this because I mistakenly thought I had lost it a week before the exam, so this product has only been used for a few days. The box has a crease as shown in the photo. Please refrain from purchasing if you are sensitive about this. It will be shipped in simple packaging.
