Using this watch band is super easy. First, make sure your watch is compatible with it. You can use it with Apple Watch Series 1 - 9, Apple Watch Ultra, and Samsung Galaxy watches with 20mm straps. To change the band, just press down on the easy - release mechanism. Then, line up the new band with the pinholes on both sides of the watch and it's done. As for maintenance, keep it away from harsh chemicals as they might damage the finish. Also, since the exact colors and patterns may vary slightly from the image, don't be surprised if you notice a little difference. And when not in use, store it in a dry place to keep it looking its best.
