I'm not familiar with the brand W7 as I haven't seen this brand stocked in Boots or Superdrug however I saw this Glam Box set in TK Maxx or you can buy these products separately online.
W7's aim is to offer high quality cosmetics at an affordable price. I like the sound of their aim and after browsing through their site, they have an extensive range of products which can cater to everyone's needs. Something that deserves a massive thumbs up from me is that they do not test on animals.
