Now on the market, most SUP storage elastic cord is close-up by heat shrink tub.
It is the cheapst and efficiency closure way.
The disadvantage is:
-1. Looks low-priced;
-2. If cord closure too tight will make nose around the board head pulled up, looks ugly especially when customer open box see their board at first time. If cord closure too loose will make storage fuction invalid. It's definately depends on packing workers experience.
Now this problem is solved by cord buckle as blow picture shows.
Why?
Because when you press the buckle, the buckle can move forward to tighten or loosen, when don't press, this buckle will stop there.
I think every SUP board need such a cord buckle!
