"It is a bit harder than my prev lip liner, but staying power is much better. I really like this smart cap, as it is different from those regular plastic caps (try it and you'll get my point). Even if i fill my lips with it, they are not dry, which is good. The lightest shade is a bit too warm for me (coral/peachy tones), thus I will go for cooler shade next time, but definitely re-buy for me."
"I love this lip liner. I use #2 and my daughter uses #1 we also both use the red one with the pop colored lipstick. I have many of these liners for almost every bag/area in the house that I need them along with posh balm and the posh gloss/lipstick. Can't say enough, love this long lasting liner, it stays on almost all day"
"I usually use a lipliner as my lipstick. Love this colour , it is hard to get a decent red lipliner. A lot of companies produce very bland tones. Really pleased with the quality glides on easily and easy to sharpen."
"After working within the beauty industry within a department store for over 20 years I purchased lip and eyeliner from yourselves I have been extremely impressed with all of the products I purchased they are excellent quality and extremely easy to use I will no longer be going back to Estée Lauder, Dior or Lancôme for these products going forward"
"Would recommend this lip liner! Good for a natural look type of day. Good staying power!"
"Wow, naturally makes my lips appear more alive & fuller paired with the balm. And really long lasting. Very impressed with these products."
"I’m new to this product but I really like it . The tip works well for a precision finish . The consistency seems quite thick the depth of colour is reassuring strong so you get a great finish . I’m definitely mature and the thing that sold me was that it wouldn’t sink into the lines on the lip line . I’ve yet to test that past a couple of hours but it really is a stunning colour and finish . Something every person that loves a red lip should have in their makeup bag ."
"Posh Lip liner 02 is luxurious and applies beautifully! I love my Posh Lipstick 02 and Posh Lip Liner 02 together!"
"I have used many lip liners before; this one is easy to apply and stays on longer"
"Excellent texture and color. Very high-quality craftsmanship."
