A few months ago, I stumbled across a tin of hand cream at the chemist that was smaller than a lip balm. I bought it out of curiosity and because the packaging was cute, and it turned out to be really good!
While I don't carry make up in my handbag, I always have hand cream and a lip balm on me. My beauty editor sister put me onto this lip balm, which she buys for me when she's in the US and the other day, I posted her a tiny tin of hand cream in return.
After carrying everything from bulky glass jars of fancy hand cream to lighter tubes, this one is extra light to carry, under five bucks and being semi-solid, is leak proof too :)
