Ozark Trail 18 oz Insulated Stainless Steel Tumbler with Swivel Handle, Tan

This 18 oz stainless-steel tumbler holds plenty of liquid and holds it in without leaking with a positive seal on the screw-on lid and on the spout (when folded). I got mine for coffee, and even the hot liquid stays put! When you lift the spout, any pressure difference is immediately released through the vent, so you won't get squirted as is typical with tumblers that have an internal straw. The large folding handle makes it easy to carry when you have a load, but takes some getting used to when drinking as it gets in the way. You have to work around it. Yes, it fits well into cupholders. The finish is pleasant to hold and the insulation does its job well. I put mine in the dishwasher, setting the straw-lid assembly straw-down into the silverware basket. That gets it nice and clean and the water doesn't get inside the insulation.
