This is one of the neatest products we have found in some time. Although it's a bit of a departure from our normal textile/fiber focus, these inkjet printable magnets are great.
Available in 8.5"x11" sheets, 4"x6" photograph size, and sheets of 10 pre-cut business cards, all of which can be printed with a regular inkjet printer. They also take markers and pens like a champ. Our fabric markers worked great! Dry right out of the printer, or minutes after using pens and markers, and permanent - nothing washes off if they get wet. The magnets are thin and easily cut with basic scissors, or our Hobby Knife Set (#HKS).
The uses are nearly endless. You can print up business cards for customers, I would even make the bet that your refrigerator is currently sporting several businesses magnets (probably pizza places). Great for kids parties where each child can draw with markers their own design, color it in, and take it home to put on the fridge. Make protest magnets and stick them onto metal things all over! Adorn your friends' metal surfaces with inappropriate images and text? All kinds of possibilities!
