This new kit makes impression casting easier than ever. It includes everything needed to make a full-sized adult shoe impression — all inside a handy plastic pouch. No more measuring and no more mess! The kit comes with 2 lbs. (32 oz.) of our dental stone and 14 fluid oz. of liquefier. With Shake-N-Cast, the mixture is always the right consistency. Simply apply pressure to break the water capsule, shake and knead the contents for up to two minutes. Next, cut off a corner of the pouch and pour the mixture into the impression.
