The Lindy Bait Tamer mesh bait bags keep live bait healthy, and can be used in fresh or saltwater. In addition to keeping minnows, shrimp, leeches, and other live bait strong, Bait Tamers also make it easier to handle, catch and transport bait. While in use, Bait Tamers won’t collapse, but they do fold easily for convenient storage. Bait stays secure with a Velcro opening, and the mesh construction provides 100 percent circulation and ventilation. Durable and washable.
