I picked this up in Jpn; you can purchase on ebay/online, but it will be 2x the price.
The formula is creamy, nonsticky, and a bit sheer, but still pigmented. It's great value if you buy in Japan; maybe 600/700 yen? This tube lasted me six months. The packaging is a bit longer for lip balms/lipsticks, but built very sturdy (you can throw in bag and not worry about it breaking, cracking, or the tube cover falling off).
I purchased shade #4, it's a dark pink similar to Revlon Lip Butter in Pink Truffle.
Yet, if you're in the US, this is the same consistency as Revlon Lip Butters, so personally I don't think it would be worth $18 off ebay. Totally worth it to stock up if you're in Japan though!
