A selection of Arabic keyboards for use with desktop computers are available for sale from sellers on Amazon.com and Ebay.com. A selection of replacement laptop keyboards with Arabic characters is available from DHGate.com. All of the sites are marketplaces that carry listings for keyboards sold by third-party vendors.
Arabic keyboards come in several different styles. Some are designed to cover an existing keyboard, either in the form of decals or stickers of the Arabic characters that correspond with each key, or in the form of a plastic sheet that fits over the entire keyboard. Others are full keyboards that have either Arabic characters or a combination of Arabic and Latin characters printed on the keys.
