Created for precision and strength, the Bauhaus Nipple Vice comes with two clamps that may be adjusted for your preferred degree of tightness using the modifying screws found at the bottom. The guidelines are covered in soft black rubber with the help of a fragile curve in the very finish which helps in gripping your skin of the subject. Ending this commanding piece is adding a one foot connecting chain that appears oh so enticing because it hangs in the captive nipples of the doll. Measurements: Each clamp measures 3 inches long, and opens to .5 " wide. Chain is one foot long. Materials: Metal and Thermoplastic Rubber TPR. Color: Silver.
