Using this product is easy. First, take out the case base, faceplate, and buttons from the pack. Place your 2.8' PiTFT and Pi in the case base. Then, attach the faceplate on top, making sure the sleek black bezel fits well. Press the faceplate firmly until it's securely in place. Remember, this pack is only for the Raspberry Pi Model B+, Pi 2, and Pi 3 along with the 2.4' PiTFT. PiTFT and Raspberry Pi are not included in this pack. For maintenance, you can use a soft, dry cloth to clean the transparent case base and faceplate. Avoid using harsh chemicals as they may damage the surface. Keep it in a dry and cool place when not in use to ensure its longevity.
