This design is sublimation and will not fade or peel as it is absorbed into the tumbler. ...THIS IS NOT EPOXY... Although sublimated tumblers are heat resistant, a dishwasher's high temperatures and harsh detergents can damage or fade the design. For this reason, it's best to hand wash them with warm water and mild soap. After washing, allow them to air dry before using them to prevent fading. Great for gifts, birthday gifts, teacher gifts ect. How about Christmas gift giving, fill mug with sweet items! Great college send off gift. These items are created by me using the finest of supplies.
