Haha, I was torn like you, but ultimately decided to open it. I was too curious to know which number I had. If they had displayed the number on the outside, I may have kept it sealed. I'm glad I opened it though, not only since I received a low number (#0057) but because this figure is so cool it warrants displaying properly. Personally, Pyramid Head is one of my favourite villains and I had been waiting for this specific figure for a long time. I had to open it
The box is awesome in it's own right and could be it's own display piece near the statue.
It's a tough call but i'd open it.
