Nice work. Thanks.
Based on the design of those fake pandas, they were made pre-2006. Most pre-2006 fake pandas have defects in eyes and nose and furs are missing the details, while the temple design and 3-dimensional details are different from the genuine.
The quality of post-2006 fake pandas are very good. However, the 3-dimensional details, especially the fur sections still can be used to spot the fake.
