This is a new, unused item. It is a set of 4 connector caps for old Shimano electric reels. *These are for Shimano's older models with an outer connector diameter of approximately 16mm. Examples include the "Digital Thana SLS Electric Maru TM3000H" and "Titanos ED6000," which are 2-pin models with a slightly thicker connector than other models. The size will not fit Daiwa 2-pin models, as it is too large. (Photos 5 and 6 are reference images; the reel itself is not included.) Please note that the size may not fit all models. I appreciate your understanding. I have included multiple photos. Please take a look. Thank you.
