Using this Gashat set is easy. First, grab your DX Gamer Driver (which you'll need to buy separately). Then, insert your chosen Gashat into the driver and start having fun with the character - specific dialogue. When it comes to the stickers, just peel and stick them on the Gashat however you like to make it unique. As for maintenance, keep the Gashats away from extreme heat, cold, and moisture. If they get dirty, use a soft, dry cloth to gently wipe them clean. Don't try to open the Gashats yourself as it may damage them. Have a great time playing with your new Gashats!
