Thank you for viewing. This is a set of 4 twin snaps for attaching two octopus egg snaps. It uses a power swivel that can withstand even large octopuses and a hook-and-snap that makes it easy to change weights! Also, it employs a combination of a power swivel & round top snap (nice snap) that makes it easy to change lures and prevents lures from coming off due to deformation. This product contains 4 sets and is a great value, about half the price of commercially available products. As shown in photo 6, you can add a snap swivel to adjust the length with the weight. (Adjustment snaps are not included) *All items in photo 1 are included. *Photos 4-5 are examples of use. Lures and weights are not included. *Returns and exchanges are not accepted except for defective products. *Although it is new and unused, there may be some minor stains. Please understand this beforehand. Shipping will generally be the day after payment is confirmed. It may vary depending on the timing. Shipping may be significantly delayed due to outings, etc., so please contact us if you are in a hurry. Thank you for bidding after agreeing to the above. Thank you very much.
