KeepCup Commuter, Insulated Stainless Steel Travel Mug with Leakproof One-Handed Flip Lid, Recycled Steel, BPA Free, Dishwasher Safe, 227ml 8oz Dark Chocolate

Leakproof flip lid: The one-handed flip lid closes to a genuine seal, so the mug travels in a backpack or a work bag on its side without soaking your laptop, your notebook or your lunch. That is the difference between a mug you trust in a bag and one you carry in your hand.
Insulated stainless steel: Double-wall stainless steel keeps hot coffee hot and iced coffee cold for hours, while the outer wall stays comfortable to hold with no cardboard sleeve needed and no condensation ring on your desk.
Fits car cup holders: Sized to drop into a standard car cup holder and slim enough for a backpack side pocket, which makes it a genuine everyday commuter travel mug. Made to barista-standard cafe measures so your order arrives exactly as it should.
Built to last, and to be repaired: Lids and seals are sold separately so a worn part does not end the mug, and manufacturing defects are covered by warranty. Top-rack dishwasher safe, independently lab tested every year, and free from BPA
