These Swabs are great for cleaning those hard to reach places. They are 5″ long and the 1/2″ wide head is a durable spongey material fused to the flexible stick. They can be used over and over again to clean inside your cage while you are wearing it. These are the best way to stay clean for long periods of lockup. Just put some soap on the sponge, insert it into the cage, and clean and flush with water. There are 10 to a pack.
