The Rambler® 10 oz Wine Tumbler with MagSlider™ Lid will let you sip your favorite wine by the campfire. This wine tumbler cup is made from kitchen-grade stainless steel which makes it puncture and rust-resistant. It features a double-wall vacuum insulation that will keep your hot drinks hot, and your cold drinks cold longer than standard drinkware. Its MagSlider™ Lid adds an additional barrier of protection to keep drinks contained and prevent heat or cold from escaping. Enjoy your most exquisite wine while camping or fishing with the Rambler® 10 oz with MagSlider™ Lid!
