This product is a convenient conversion grip for when you want to use a long keiryu rod in a shorter length. Even with zoom function rods, the adjustable range is limited to just over 1 meter from the total length of the rod. With this product, you can change a 6.3M or 5.4M rod to 3.6m or 2.7M to suit the situation and field! You can also use your existing nobe竿 (fixed-line rod) as a short tenkara rod, so you can convert your existing keiryu rod into a tenkara rod without buying a new one! This is a budget-friendly item for anglers! It's also popular as an add-on grip that's easy to use for those who find short nobe竿s too thin and difficult to hold! It can be used with all extending nobe竿s! How to use: ① Remove the cap at the butt of your rod and take out the amount you need for the desired length. ② Attach the plastic spacer included with the grip to the rod. ③ Set the rod into the grip. That's it! Easy to use in just 3 steps! Recommended for those who don't want to carry extra gear, those who want to fish for anything with their favorite rod, and those who find it troublesome to prepare multiple rods for different fields and targets. Wouldn't it be convenient if you could change the length of the same rod after fishing in a large river and then going to the headwaters? The grip is made of EVA material, so it feels good in your hand and isn't cold even in the winter. Since the grip is the same when used in a shorter length, the feel of the grip doesn't change. By attaching it, the center of gravity of the rod is closer to your hand, making it less tiring. *The color of the plastic parts for adjusting the thickness may vary.
