Spawn Sacs Regular Spawn Sacs are made with soft-textured natural spawn eggs with good milking action to attract salmon, steelhead and rainbows like nothing else. Drift these enticing clusters along the bottom and it won't be long before they are picked up by your quarry. Use them by themselves or in conjunction with a drift bobber. Hand-tied in soft nylon mesh cloth. 6-8 eggs per sac. Not for Human or Pet Consumption.
