That company is typical of large numbers listed on Alibaba, claiming to be manufacturers, but they are in fact a trading company. They claim to have 10 years experience, but the business was registered in 2013.I think these wooden sunglasses can be the alternative.

Sell it.
Never believe what you read on a vendor's page on Alibaba until you have checked it out for yourself. There's a lot of smoke and mirrors there. It took me less than 3 minutes to find the true story.
It is worth knowing, not only for assessing trustworthiness, but also because of the fact that traders will rarely be able to give you a price as good as you can get from the actual manufacturer. If they can, it is usually only because they are selling closeout stock. That's no way to start a long term business.
