Thank you for viewing! (^_^) Here are 5 rod rests for crucian carp fishing, to be attached to the tip of a rod stand. The dimensions, measured at the center of the rod stand insertion opening, are approximately 7.5mm, 8.5mm, 10mm, 7mm, and 10mm from left to right in the photo. *Please note that these measurements are approximate, as they were taken by an amateur. Please understand that these are used items. Please refrain from purchasing if you are overly concerned about condition. Free shipping. How about it?
