Thank you for viewing! This is a base for smelt fishing! Non-slip sponge mats are attached to the lab jack, and a plate is attached so that magnets can be attached! Grease is applied to the adjustment screw part, and adjustments have been made to ensure that there is no play and that the moving parts move smoothly! This is a new, unused item. There may be small scratches! Please understand. #smelt #wakasagi #pond smelt #base #handmade
