This may sound as if it is some sort of trick, but it’s not. This coffee mug can really help you to remember things because you would have written important dates and other things onto the side with the special pen. Once completed the ink wipes off and you start all over again, so coffee really can help with your memory!
These are the details for the excellent Memo Mug;
We’ve lost count of how many times we’ve had a brilliant idea on our coffee break, but then, uh, where’s a pen? If only we had been using this ceramic mug that doubles as a message board. It’s even got an integrated pen holder so no good idea goes forgotten. Measures about 4″ tall.
Priced at $18 in the US and around £12 for UK coffee drinkers
