The Therabody Wedge Hand-Held Massager Attachment is designed to target specific areas like shoulder blades and IT bands. Featuring a unique, thin wedge-like edge with a medium impact level, this attachment delivers a firm touch suitable for "scraping" and "flushing" techniques. These motions help promote circulation and remove lactic acid buildup from targeted muscles, which can lead to soreness and stiffness. The Therabody Wedge is made of closed-cell PU foam, a durable material that is easy to clean with disinfecting wipes for optimal hygiene. It is compatible with various Theragun massage guns, including the 4th Generation PRO, Elite, Prime, mini and the 3rd Generation G3PRO, G3 models.
