Sattler TRI GRIP, Wedo

The Dr. Barbara Sattler's more advanced ergonomic writing aid favors optimum grip and reduces the strain on the fingers when writing. A wrong holding position is hardly possible due to the triangular shape and the clear positioning requirement for the middle finger. This is supported by the nubbed and domed bottom. The TRI GRIP can be simply pushed up to a diameter of 12mm on writing instruments, a hobby knife, brush etc.. The pleasant touch material is free of toxic substances and provides for both right as well as left-handers (marked as "R" or "L"), and also arthritis patients a relaxed holding and writing position. Length: 3.4 cm. Supplied in container of 50 pieces, assorted colours.
