Difference between Chinese BOX Razer Viper mini and only english box Razer Viper mini and 'V2' at th

Hello, in my country there are 2 box versions of Viper mini. I want to buy this mouse very soon. TL;DR One box English + Chinese. Serial Number has V2 at the end. Another box only English. Serial number don't include V2 at the end. Both latest productions of 2021. Inconsistency? Different outsourced manufacturers? Details: One has English writing and Chinese. And its S/N includes the normal PM-YY-MM-??-??-?? numbers. But at the end of the Serial Number, it's written V2. They are Production of 2021 and month April. Is this legit? My country also has Razer Viper mini available with English ONLY written only on the box. But the Serial Number don't include a V2 at the end. These products also have 2021 year production date and near April month. As much as I have heard, both the boxes come from China. Not Taiwan. Both latest production, one has V2, the other doesn't. Is this inconsistency in quality? I know this much that, the Serial Number can be registered on Razer official website. Can someone (ideally from within Razer) confirm whether the V2 at the end of the Serial number is just added in order to make the product seem more updated or it's originally part of the serial number? Also, which version of the Razer Viper mini should I get? I will be buying this mouse very soon. Please share if you know anything related to the possible differences.
