These containers are super popular with all the biggest Slime shops! Their unique low profile shape is especially perfect for any crunchy Slime that has the addition of beads. It allows the customer to remove the Slime from the jar without hurting your hands. Of course these jars work well for any other type of Slime as well, like butter, clear or cloud. Each jar comes with the lid and once screwed on creates a perfect air tight seal!
