This is an anchor net for ayu (sweetfish) lure cans, tomo-kan (live bait containers), and hikibune (drifting boats). The size is 30cm x 30cm. The cut edges are heat-sealed. As shown in the photo, it's normally small, so it won't get in the way even if attached to a lure can. The length of the cord is just right for my use, but I'll include a 2-meter cord as a bonus, just in case.
