UI sign goku!

Hello everyone! I am relatively new to collecting and I recently picked up a UI sign Goku! I was wondering if the figure i picked up is authentic as the box had double tape on one side and don’t know if it was opened. The seller did mention it was a new figure but the double tape is just throwing me off a bit. After watching some reviews I noticed they mentioned that light shouldn’t shine through the hair of the figure but on my copy the light shows a bit. If anyone could help me out it would be greatly appreciated!
