・ Features rubber seals to prevent the entry of dust and sand, extending bearing performance. ・ The size is the same as the bearings and collars that come standard with Daiwa S-type and Shimano A-type knobs (except for some). ・ Compatible with 4mm handle shafts of Daiwa and Shimano. Perfect for those who need extra bearings when replacing knobs, or for those who want to add bearings or replace plastic collars. ・ Additional quantities can be accommodated, so please inquire via the question box. I will make it a dedicated listing. MR74 DDL-740
