Daiwa I'ZE FACTORY RCS Custom Spool 2004. Compatible with Certate, Luvias, etc. Having a spare spool is convenient for ultra-light games with a relatively high chance of light troubles, such as Mebaru (Rockfish), Ajing (Horse Mackerel), managed fishing ponds, etc. I cannot answer questions like "Does it fit reel ⚪⚪?" This is a near-mint item. No issues. Shipping included. Price is not negotiable. Thank you.
