Its never a good idea to leave a cold beverage setting on a table without a coaster, especially during a sweltering hot summer like the one we are having this year.  Not using a coaster is a great way to ruin the furniture (I’ve accidentally done this before myself) if you aren’t careful.

Well, if you are a Portal fan and are in need of coasters, I have found the coasters for you!

The awesome people over at Entertainment Earth are selling these Portal warning sign drink coasters for $19.99.  They are quite awesome if you are a Portal fan, but for those that aren’t, I recommend checking out the other coaster sets that I have posted in the past like the Legend of Zelda Triforce coasters and the Final Fantasy beverage coasters.

Pass this along to any Portal fans you know!  Like us on Facebook too!
