Three sizes of bars to choose from. These are solid moisturizing bars, like a bar of soap but a bit softer, that you take out of the container and smooth on to your skin exactly where you need soothing. The heat from your skin melts the outter layer as you use it so you just put on as much as you need. I love it for my elbows as it eventually creates a well in the bar that my elbow just fits in to. the 35g size comes in a tin, the 14g & 9g sizes come in ziploc baggies and we do sell separate tins for those if you prefer them in a tin. We even make a special one for pets, you can rub it on their paws and their noses.
