Ceramic printed coffee mugs make an excellent promotional gift or merchandising item. They give your company logo or message a billboard-like exposure in the workplace that is on show for all to see for many months or years, making them a very cost effective promo item. Ceramic Mugs are manufactured from a variety of materials resulting in mugs of differing quality. Stoneware is low cost, the mugs are generally handmade so some minor imperfections may be evident, however these are suited to many low budget promotions. Porcelain mugs are made from higher quality clay and are fired at higher temps giving a more durable and better finish than stoneware.
