hqueen--can you tell me what you mean by a lotion bar?
My balm is 3 oz in a round tin. The surface seems about as hard as lip balm, but once you gouge into it you're able to get out more balm for heavier use. My balm is made with olive oil, sweet almond oil, castor oil and beeswax. My lip balm currently is palm kernel oil, olive oil, safflower and grapeseed oils, beeswax, castor oil, vitamin E and EOs.
I sell mine for $9. People actually don't bat an eye, amazingly. Not too many sell, and they last forever, but people who get hooked come back for more. And they're so versatile--I use mine for lip balm, cracks in hands and feet, dry skin, around my eyes at night, on my kids' chests during colds (with certain EOs). Could be used on diaper rash.
