Mustad 39932XNP-BN Barbless 4X Strong Circle Hooks - Size 11/0

I have been fishing for shark (mainly blues) off the south west of the U.K since
1974 . In the early days I used Mustad Seamaster
J hooks size 10/0 or 12/0 usually with the barb filed well down. In 2004 I visited
Mauritius and Kenya and was introduced to circle hooks which
I started using for sharks in U.K waters. These circle hooks were all barbed , which
was not very good as all sharks are returned as unharmed as possible.
Last summer ,2018, Mustad supplied some of these barbless circles to the Shark
Angling Club of Great Britain . I got hold of a couple , rigged them and found them
superb.
Despite searching high and low I cannot locate these in the U.K. at all . Thanks to
you selling these on Ebay I will now be able to make rigs for myself and friends and
Go catch and release unharmed a lot more sharks.
