We are please to offer you this handy Travel Shaker. All you do is remove the sifter top, pour a small amount of your Claymazing to the jar, replace the sifter and the red over-cap, and you are good to go! The Travel Shaker is virtually crush-proof, shatter-proof, unbreakable, and is also reusable. Thank you for your suggestion, you asked, and we listened! We hope you enjoy the convenience of Claymazing on the go.
