These are pliers exclusively for Biot, in which the position of the plier body is parallel to the material.The tip is thin, making it ideal for wrapping short goose biots, etc.The rubber parts of the joint have moderate elasticity and can be expected to function as a shock absorber.The inside of the tip is sandblasted to ensure that the enamel biot is retained.The inside of the pliers has been sandblasted to give it a non-slip finish, allowing it to securely hold goose biots, etc.The edge of the tip is rounded all around to prevent the goose biot from cutting at the edge.The shock absorber and O-ring expand and contract to the extent that you do not lose the delicate sensation of your fingertips.The position of the plier body is parallel to the material, allowing you to create a biot body without twisting.
