TRIPLE INSULATED TECHNOLOGY - the Albor stainless wine tumbler has triple insulated stainless steel vacuum technology, with an inner layer of copper preventing heat transfer to the outer walls. This allows an additional 4 hours of insulation over other wine tumblers with lids, keeping hot drinks hot and cold drinks cold.

100% LEAK-PROOF TRAVEL WINE GLASS - included with this stemless wine tumbler is a splash resistant spill proof sipper lid with a straw, a sipping friendly drinking hole and an ergonomic slider for easy closing. Plus the wine glass tumbler set comes with an additional bonus lid without the slider, for those times when you want quicker access to your beverage.

BONUS STAINLESS STRAWS AND ICE CUBES - in addition to the bonus lid this insulated wine glass set also includes 2 stainless steel straws (1 straight and 1 bent) with a cleaning brush and linen bag for storage plus 6 reusable ice cubes.

EASY TO CLEAN AND LONG LASTING WINE CUPS- every part of the BPA free stainless steel wine tumbler set is easy to hand-wash, making cleaning a breeze. The exterior of our stainless steel wine glasses have a durable color coating that will not fade, peel or crack, plus the 304 grade stainless steel in this insulated tumbler is rust resistant.

100% MONEY BACK GUARANTEE - ensures your satisfaction. If the Albor wine mug set does not meet your expectations, return it for a full refund. No questions asked.
