WowMugs from the Redbows Promotional Mugs range. This Durham style ceramic mug has a heat sensitive coating on its outside which is personalised with a dye sublimation print. When a hot liquid is poured into the mug, the heat sensitive coating becomes transparent, revealing your message underneath. As the mug cools, the message fades as the mug returns to its original colour. This Durham style mug can also be over printed with a permanent message. Why not ask our Design Studio to send you a Virtual Visual? All we need is your artwork and we can send you back a free of charge proof showing how your logo and marketing imprint could look on this exciting promotional item. If you do not have any artwork, our design team will be more than happy to create this for you.
