Go into any office kitchen and you will find promotional coffee mugs.  It seems that everybody that has a desk that they work at on a daily basis will also have a promotional coffee mug.  Where they all come from is anyone's guess, even though they are emblazoned with the name of some company or product, the owner of the mug might have no idea how they came to be in possession of it. 

Cups and mugs are a great way to promote your business as they are used on a daily basis and are generally left in places others will see them, be it on a desk or in the communal kitchen area of an office. Hot drinks are an essential part of the working day, so providing a mug that doubles up as an advert is a great way to get constant promotion. They can be made up cheaply and quickly by loads of different companies, most of who will offer you a great online service where you simply send your design to them, approve the draft they send and within a few days your promotional coffee mugs will arrive. Of course you have to very carefully check the proof they send you to check as having a silly spelling mistake on something that is going to be in circulation for a long time is going to be a bitter pill to swallow and it happens, trust me I've seen it where I used to work!

Promotional coffee mugs can also be used as mementos for events such as fun runs or even prizes for quizes or competitions. Once someone has that cup in their possesion it is bound to do the rounds of friends, family and visitors.

You can get some great novelty features for these types of things too - cups that change colour when hot liquid is poured into them, or perhaps the logo of your company only appears when the cup has hot liquid in it. Simple things like that make the cup all the more desirable. It's amazing how possesive and jealous people get when it comes to things that seem to fall into the category of "cool office toys" and promotional coffee mugs all too often find themselves in this category if they are designed well and look great.
