It is using from about 20 years ago, but this is not a problem and may be waterproof This time, was the first to buy. Person of the site, I really size of 1/8 wanted, was in because it was so that there is no handling, of different size ones. Please increase the more variation. At the same, at the time of packing of luggage, do not bend the tube. Tsutsubure was the place is, you will not return to the original. I ask whether the long shipment of remains round.

Shrinkage ratio of about 4: it is very convenient to 1 because of the electric wires having a step connection. In addition good adhesion is obtained by internal adhesive by heating, tensile strength can also be used with confidence because the increase. In addition, great also waterproof effect by the adhesive.
