Mugs can be used for awards, for special occasions or pre-planned events. Use your photo and sentiment or select a photo from our online gallery. The mugs have a hard, durable coating. Dishwasher safe. Don't forget to check out our large mug sentiment coaster tiles (6x6") for the larger coffee and hot chocolate mugs. A mug and a coaster makes a great gift! TIP: Most horizontal photos do well on mugs. Verticals are generally used on either side of the mug. You can send 2-3 different vertical photos - if you wish or use two photos with sentimental text in middle.
