Premium dycem, slightly thicker and with our IPA logo. Synthetic 5" x 5" sheets to improve gripping and reduce slippage during Functional MobilizationTM. The increased thickness helps to increase tolerance to palpation in patients who have significant tenderness over bony prominences. Care: When your product gets dirty and dusty, simply restore the Non-Slip properties by washing in warm soapy water and allowing to dry.
