Do you sometimes feel as though magnets work like magic? Well, they happen to be extremely useful in everyday life, where there are countless ways where magnets help keep things together – literally speaking at times, too. How about checking out the $6.29 Flipside Reversible Dishwasher Sign that is pretty much self explanatory? This unique sign will be placed on the outside of your metal dishwasher, letting you know whether the stuff inside is clean, or needs some washing. Specially designed after a retro “Sorry We’re Closed” sign, it says, “Sorry We’re Dirty” on one side and “Come In We’re Clean” on the other, doing away with the need for you to open it up and check the inside of the dishwasher itself.
