The double vacuum insulation design prevents the transfer of heat or cold and keeps your drink is hot or cold for longer. When filled with hot water, the cup will never get hot! The 2 in 1 screw-on lid with a silicone seal prevents leaks. The spill-proof flip-top lid is for easy drinking of hot drinks; the straw opening is easy to drink from with a flick of your finger. It can be opened and closed with just one hand. The frosted material of the cup provides a secure and comfortable grip, while the rubber on the bottom prevents slipping. Good insulation and the right size make it a good choice for travel, office, car and elsewhere. With its beautiful color and elegant design, the 2 Pack is a great gift for yourself and your friends, family and more. Up to 14 oz Coffee Travel Mug & Tumbler 2 Pack
