Input:
When trying to keep liquids hot or cold when on the go, spillage or leakage is always an issue.  This Stainless Tumbler solves the problem beautifully.  Once the hot/cold liquid is placed into the tumbler, simply screw the sipping lid on and then add the sealing screw cap.  To use, unscrew and remove the screw cap and sip from the sipping lid.  The screw cap + sipping lid when screwed on correctly, make this totally leak-proof.  And it will keep coffee hot for up to 6 hours!
