These are dongs with two penetrative ends, which are often penis-shaped but can quite often be probes or other shapes.  Usually longer than regular dongs, double dongs can be U-shaped, straight, or bendable.  The U-shaped varieties can be great for double penetration, or twin use between partners.  Straight double dongs are great for used between lesbian partners simultaneously, and generally allow some degree of flexibility, although they are commonly used as an extra-long dong.  Bendable double dongs can generally be used for all of the above uses.  We recommend using plenty of lubricant, and a non-alcohol-based toy cleaner after use.  More info on double-ended dongs
