This is a special dip net (tamo-ami) for catching glass eels (shirasu-unagi). The stainless steel frame has an angled opening at the tip, and it's a square, bowl-shaped, moderately deep net. For riverbeds, revetments, and the edges of blocks— This shape is designed to be inserted into the "corners" where the eels have nowhere to escape. This is a practical, single-minded dip net designed for use in the field. The approximate size of the net is: 18cm long (including the diagonal part), 16cm wide, and 6-7cm deep, with a square bowl shape. It uses a 20-mesh net with a wire diameter of 0.29, and the net is secured with stainless steel wire before the adhesive is applied. Because of its square shape, it's easy to use along walls, corners of blocks, etc., on riverbeds and embankments. *All items are handmade with care and soul. Please understand that due to the handmade nature, the size may vary slightly from piece to piece.
