Hollo Elastic is available in 7 different strengths to suit all carp fishing situations from 7H up to a very powerful 19H. Thoroughly tested by our consultants, Hollo Elastic comes in 3m lengths in a sealed bag that ensures it stays in perfect condition. The ratings correspond to normal elastic ratings, so a 13H rating is between 12 and 14 normal elastic strength. Due to a special manufacturing process, injecting lubricant inside the elastic is not required.
