This is the finest tying material on the market. It is available in .004, .006, .008, .012 mil. and comes in both 1/2" and 1" sizes. The 1/2" small rolls are custom slit for use in the HT-B tapener and the larger 1/2" rolls are used in the HT-B2. When proper strength tie is used, it will not girdle or cut a tree or vine. It is strong, pliable, color fast, and does not ever need to be retied. For staking, tying, training, or flagging, there is no finer product.
