Finally an accurate way to see if your building our favorite Twisted Hobbys EPP Foamie square and true. Measures 3" on each side, comes with protective tape over square.
This is a must have for assembly.
I purchased this building square because a buddy of mine told me I should get one. So let me tell you I am glade he did. It helped me keep my model square and straight. My model was perfectly straight this time around. I should have purchased this sooner. Thank you TH for another great tool!
