How big is the Tōk?

Each Tōk is 3.5” (89mm) long, 2.9” (74mm) wide, and 0.7” (18mm) deep. It weighs 4 oz (115g). So think of it as pocket-sized. (The average men’s jeans pocket is 9.1” deep and 6.4” wide and the average women’s is 5.6” deep and 6” wide.)

Oh, and the holes are: ½” (13mm) diam. x 3.3” (84 mm) long.
