They are a SaleHoo-recommended supplier and have been verified to be safe for you to use and to only offer authentic products. If you are unsure though, what I suggest that you do is contact them directly, enquire about the authenticity of their products and request for a proof of authenticity if deemed necessary.

They don't have any reviews yet, though. I did a Google Search but couldn't find any. So if there's anyone who purchased from this company before and who can provide some feedbacks, it'd be greatly appreciated! :)
