Contents: Magnets (weak magnetic force) x 2 Large plates (6.5cm x 4.5cm) x 2 Prevents tipping, dropping, and reel lift-off when using electric smelt reels. Compatible with both Lake Master and Crystia reels. Also compatible with Crystia AIR. (Similar to the genuine magnets, there will be a slight gap.) This product has a (weak magnetic force). The genuine product has a strong magnetic force, so this is recommended for those who are concerned about operational issues such as delayed hooksets or difficulty in attracting fish. It can be used without problems even when boat fishing in waves and wind. For those who prioritize fall prevention, or when using weights of 12g or more, or in areas where large unwanted fish are likely to be caught, we recommend the normal magnetic force version. *Magnets only are 650 yen each. *The double-sided tape may come off easily if used immediately after application, so please let it sit for a day to allow the adhesive surface to settle before use.
