Perfect examples of winning simplicity in design, we're longtime fans of Three by Three's unobtrusive magnet strips and superstrong magnets. Though not new, their "Anywheres" are self-stick mini magnet boards that come in eight different iconic shapes. With circles, stars, arrows and more, the little magnet boards are a way to organize on cramped walls and add either a hint of color or an understated design element depending on which you chose.
Anywheres have an adhesive back and are made from the same powdercoated metal and come in the same modern palettes as their other products. Several items from their line (the organizer shelves and mail holder/keyhooks are good buys too) are available from Fridge Door.
