For example:
beautyshoppers.com/collections/beshe-hair-wigs-weaves/products/bs-lace-lxlp-260?variant=4735571585
That is my favorite BeShe wig model, the LXLP260. 26" of pure thickness and silk.
It has a lot of websites. If you´re from European Union, better in a website from UK, more expensive, but without customs.
If you´re from USA, you has lots of local websites. Just type "Buy BeShe Wig" in google.
