I have one of these Plushglasses. I just got it today. Ordered it from ebay. Anyhow, it does make your lips tingle. Not as bad as lip venom, but still there is a tingle. I didn't notice any plumpness in my lips. The color that I have (full for you - shimmery raspberry pink/mauve) is very gorgeous in the tube, but is very, very sheer (clear pretty much) on my lips. I am still undecided if I like it or not.
