With this rigged winding spool, you can solve the problems mentioned above in one shot!! Even those who have never used a rigged winder can rest assured! Includes instructions!! The large-diameter spool of M size, 140mm in diameter, reduces the tendency of the line to curl. When taking out the rig, put your finger in the hole in the center of the spool and pull out the line. The spool will rotate, and the line and hook will come out smoothly without tangling! Also, because of the structure of winding the line onto the spool, the line doesn't get folded like with a regular rigged winder, so your catch won't decrease, and tangles are less likely to occur. The material is PP, so it's water-resistant. After fishing, you can wind up the rig, soak it in lukewarm water for cleaning, and remove the salt, which makes the rig last longer, making it very economical. I use it myself and have excellent results with bottom fishing and float fishing rigs. Once you use it, you won't be able to do without it... Of course, for those who make their own rigs, and for those who buy rigs, using this will make your favorite rigs last a long time, and you won't be able to do without it! You can not only wind up rigs but also wind up and store the main line from your reel, or wash the spool itself. The ways to use it are endless depending on your ideas! For example, when doing jigging, winding, or fly fishing, you can pre-tie the necessary leader to a snap and ring, secure the necessary leader length, cut it, and wind it onto the spool for storage. This prevents time loss when replacing the leader and is useful for securing your hands during night fishing and preventing seasickness on boat fishing trips. Due to the price being at its limit, we cannot accept price negotiations. Thank you for your understanding...
