What is the difference between online and offline sales?

The products are actually the same, the difference is the sales channel.Because of the differences between the channels and laws for online and offline, the differences come as follows:

offline sales enjoy the "three guarantees", online sales can be returned and changed without any reason in 7days. For offline sales, you can return them for non-human-induced quality issues in 7days, and you can return and change them for non-human-induced quality issues in 15days. Please kindly contact the sales channel for return and change. Nut Technology is responsible for repairing quality problems. Hotline 400-660-6873.
