The beachflags are always finished on the leftside with a tunnel. On the top of the tunnel is an extra solid part so the beachflag itself does not get damaged by the flagpole.
Beachflags made from normal flag material are finished on the left side (opposite side of where the flag tunnel is) with a hem finished with double stichting.
Beachflags made of longlife material are finished on the left side with a lasercutting method. This means the flag gets cut off and heat sealed together. This means that longlife material does not need hemming. This also expands the lifetime of your beachflag.
