Fujifilm also sells the newer Instax Square SQ40. It’s similar to the Instax Square SQ1 but with a vintage look that’s more visually striking, yet it’s also more expensive at $199.95. Given it produces similarly good-quality photos, I’d recommend the Instax Square SQ1 or the more capable Instax Mini Evo for $50 more.
