Glass water bottle with stainless steel lid on top and bottom of the bottle.11 inches tall and holds a little over 16 oz of liquid. Stones do not mix into were the liquid goes, it does unscrew at the bottom to open to see the stones or change them out if you wish to. Hand wash only, high temperature glass. You can use cold or hot, I'd let the hot liquid sit for a few minutes before transfering into the bottle.
