A protective case for a product, such as a tambourine, having a predetermined configuration includes a clam shell housing generally configured to conform to the shape of the product. The housing is dimensioned to receive the product with clearance. The clam shell housing is formed of two clam shell members that are hinged to each other so that the clam shell members may be separated to allow the product to be inserted into or removed from the case. A suitable lock is provided for selectively locking the clam shell members to each other to prevent a separation of the clam shell members. A handle suitable for gripping is provided on the housing for carrying the case. Positioning members in the form of stabilizing walls are provided within the clam shell housing for positioning the product and stabilizing it against excessive movements within the clam shell housing when the clam shell members are juxtaposed in a closed condition of the clam shell housing. The product is preferably maintained in a generally fixed design position within the clam shell housing where the protection of the product is enhanced. By making the clam shell housing from a transparent molded plastic material the protective case can also serve as a display case through which the product may be viewed.
