Thank you for viewing! (^_^) This is a set of two rod rests for crucian carp fishing, to be attached to the tip of a rod stand. The dimensions are approximately 7.5mm and 8mm from the center of the rod stand insertion opening, as seen from the left in the photo. (Measurements are approximate due to amateur measurement.) The left rest in particular is a very eye-catching rod rest that makes use of natural shapes. Please understand that these are used and handmade items. Please refrain from purchasing if you are sensitive to such things. Free shipping. How about it? (^^) #CrucianCarpFishing #RodStand #HerabunaFishing
