Polaroid pictures have been making a comeback, but there's still nothing more convenient than snapping a picture on your phone. Now you can combine the two with the Polaroid ZIP Mobile Printer, which connects to your iOS or Android phone or tablet via Bluetooth to wirelessly print colorful 2x3 photos. The corresponding app allows users to edit photos with text, emojis, and more before printing. Now you can finally send grandma a printed picture as easily as you can post to Instagram. Available on Amazon; $130.
