Rest assured, this is a factory-produced item, not a handmade one! We created it from scratch by making a mold of the parts from the genuine product. Ships within 24 hours. Compatible models: It should be installable if the part number for the pairing press plate from the parts list of 16.23 Larissa, 16.23 Despina, and 17.22 Hyper Force is 13LOE. It should fit 16 Larissa~, 16 Despina~, 17 Hyper Force~ and later models, but please purchase at your own risk. Please research the compatible models thoroughly before purchasing. ★Additional Note: Does not fit compact models. If you have the sound modification done on Mercari or Yahoo Auctions, it will cost over 8,000 yen. You can remove the reel's brake core yourself and install it without modification using the original two screws, but you will need a special Shimano lever brake tool to disassemble the brake core. (Installation takes about 5 minutes) You can bend the sound-producing spring to your preferred tension. Since it can be installed without modification, it can be restored to its original state after removal. I previously purchased and used sound-producing parts, but I was a little dissatisfied because the sound was quieter than Aorista, although it was still loud. This time, I improved the reel's explosive sound (gentle on the brake core, so less wear) and had the sound-producing parts manufactured in brass at the factory, so I think it's more reliable than a handmade product. I heard that someone with slightly impaired hearing couldn't hear the sound at all when they requested sound modification from a famous sound tuning shop, but they were happy that they could hear my sound. If you don't understand, you can search for "reel sound modification" on YouTube. Even beginners should be able to understand it quickly. Sound modification is at your own risk. Will be shipped within 24 hours (Excluding Golden Week and Obon) *Returns and claims are not accepted after purchase.
