This is the model that started it all. Introduced in 1975, the Standard BSE Model has taught three generations of women how to care for their breasts. Soft BIOLIKE 2 mimics the feel of real tissue and palpable lumps teach fingers how to locate potential abnormalities. Its non-palpable lumps can be seen with a penlight only, underscoring the importance of mammography. Model comes with case, slipcover, and penlight.
