Instagram helped make square images a thing again. The Fujifilm Instax Share SP-3 SQ Printer helps bridge the gap between IG and a real Polaroid. Using a wireless connection, it can print out high-res, 2.5-inch square images straight from your smartphone in just 13 seconds. It lasts up to 160 prints per charge, and the companion app lets you add filters, text, and other formatting on-the-fly. Available in black or white.
