The Semmes Weinstein Monofilaments

This cleverly designed set, consists of 6 color coded monofilaments, with the following application forces   green 0.05 g, blue  0.2 g,  purple 2.0 g,  red 4.0 g, orange 10 g,and pink300 g).  The monofilaments have been produced in accordance with the specifications established by Bell-Krotoski in 1990. When assembledthe monofilaments, rest on a bar and are ready for testing.  Once the test is complete, replace the monofilaments in their individual tubular case (which also serves as the handle during testing) and place them in the plastic envelope and they are protected and ready for the next use.  This pocket sized set is practical, durable and affordable.  For prolonged durability, the set contains 4 green, the most delicate, monofilaments. These were tested by a therapist here in Switzerland in the clinic and given a thumbs up!
