The authenticity of Bandai Gundam models is mainly distinguished by logos, packaging, materials, and prices.

1. For genuine Bandai Gundam models, you only need to look for the BANDAI logo with red background and white letters in the lower left corner. Pirated copies will not use Bandai's logo and level mark. Level logos such as HG, RG, and MG are also unique to Bandai. In addition, domestic imitation models have their own brands.

2. The printed introduction on the outer packaging of genuine Bandai Gundam models is all in Japanese, and the specific details will be more detailed. There will be proportions and Japanese words on the front, such as 1/100 みて, and words similar to BANDAI 2008 MADE IN JAPAN on the back of the package. Domestic pirated copies will write an introduction in Chinese characters, and the content of the model introduction is relatively rough.

3. The internal packaging of pirated model panels is usually multiple assembled panels stuffed into a plastic bag. The genuine ones can have up to two assembled panels per bag, and some boxes also contain foam plastic. The parts of the genuine Bandai BANDAI are fine and all are ready-made before being assembled.

4. Genuine Gundam models are made of resin, while pirated ones are mostly made of plastic, and the workmanship is rougher than the genuine ones in all aspects.

5. In terms of price, pirated Bandai Gunpla models generally sell for less than half of the genuine models.
