Teaching models available in three different breast (cup) sizes, because all women are not the same. The set includes small (5 oz.), medium (9 oz.), and large (28 oz.) models. Each model contains five lumps which, just as in real life, are more difficult to detect in larger breasts than in the smaller breasts. Each model is washable with soap and water. A must for any comprehensive teaching program. Includes slipcovers and carrying case.
