At DabJars we're quasi-famous for our Silicone Jars. Why? Because we get them freshly made just for us. If it's got the DabJars logo on the cap, you know your silicone container is made from 100% safe food grade silicone. These are approx 1.25" x 0.85", and hold 5ml. They have pop top caps, since we all know screw caps on silicone don't work. Don't take a chance with your precious concentrates, buy from DabJars! You'll be glad you did.
