・For those who find the standard 2.5mm bearings and collars too thick, or for those experiencing knob rotation issues or a rubbing sensation, please replace them with these and adjust with shims. If you need even thinner ones, please purchase the 1.6mm thickness offered in this listing. ・These are the same size as the bearings and collars that come standard with Daiwa S-type and Shimano A-type knobs (excluding some). ・Suitable for 4mm handle shafts on Daiwa and Shimano reels. Perfect for those who need additional bearings when replacing knobs, or for those looking to add bearings or replace plastic collars. ・We can accommodate requests for additional quantities, so please inquire through the question section. We will make the listing exclusive for you.
