I kept it displayed in a glass case. It's clean, with no noticeable stains. However, when I turned it over to take photos this time, I noticed some imperfections – I'm not sure if they're chips or just part of the shell's natural characteristics. Please take a look at images 5 and 6 and understand before purchasing. It's barely noticeable when displayed. Please see image 1. Size: Measured at the longest points, approximately 9cm wide, 13cm long, and 9.5cm high. Thank you.
