It is easy to take out the end of the string as soon as it is understood. The string is also durable, so you can easily work at the summary. I do not know the durability, but I think it is a good product.
Until now I bought it in Cornan, but the stiffness was hard and the stroke was too tight to be very difficult to use, but I got easier to work with using this paper cord. I hope the prices go down a little.
