I built it carefully and it took about 3 hours to complete (´・ω・)ノ
The problematic C-funnel sticker took about 10 minutes, so I think it's a good idea to aim for 70 minutes to complete the rest of the main body, including posing and checking.
It's a really well-made kit, including the effect parts, but it looks like it will take a long time to complete, so it will probably be quite difficult to certify (´･ω･`)
