【Condition of Item】 This item has never been used for actual fishing. It is a F-type top guide. It features a high-tensile titanium frame / stainless steel pipe + Sic guide. This is suitable for rod repair, or for those who find micro guides difficult and want to increase the size. (For reference, the inner diameter of the ring was approximately 5.5mm according to my digital caliper measurement) 管g2403610s180ypm
