How many times has your mother, wife, or girlfriend yelled at you for putting water rings on her furniture? Now you can fight condensation and earn huge geek points at the same time.

These handmade Space Invaders coasters have six unique designs, feature handcrafted shellacked wood, and, best of all, they'll guard your favorite tables from the liquid ring of death [via ThinkGeek]:


The downside is that the set of six will run you $60! I know someone made these with care and all, but why do I always have to go broke to show how cool I am? Sweet Space Invader coasters: $10 each. Not getting yelled at for letting your drink sit too long: Well worth it.
