Metallic Print. But, why go full metal you ask? Metallic finishes make photos look next-level fab, reflecting just the right amount of light (and in all the right places). Naturally, they’re more water resistant than paper – which make these a great option for those looking to display their photos outdoors or in humid areas like the bathroom. This 30x40cm print is 3mm thick and arrives ready to hang on the wall. Convenient and classy, what do you know.
