Its been stated quite a bit here before but I'll make it aware again. Me and PPL co-own a warehouse in China. We also co-own a small factory we are making right now for cheaper test production. We are also cousins.
If you've received raws that have the same numbering order as PPL, its because in order not to confuse our workers, we number the raws the same. We just keep them in different fridges. Strangely enough, we buy from different factories on some of our raws because I prefer the pricing structure of other companies. (Some are way more cheaper in more bulk, which compared to my cousin, I simply cannot afford.)
Your information is never shared beyond anyone outside the warehouse. We print your order out with a special number sequence for the workers to refer to, (without your address) and then your actual address information is given to the courier, of course, for shipping. Beyond that, nothing more.
