The upmarket matte finish on this coffee mug gives it a warm feeling. Laser Engraving removes the black surface to reveal the ceramic below. This is a subtle, elegant branding method and provides longevity for the logo or message being branded, as it will never come off or fade away. Just add ground coffee and hot water to the plunger to make yourself a satisfying mug of coffee.
