The ID Millennium Lube is a concentrated formula that will only take a few drops to get things slicker and more stimulating. One of the great qualities of this lube is that it can even be used while you're having fun in the bath or shower. The ID Millennium Lube is a silicone-based lube. That means it's not recommended for use with silicone toys. It is, however, latex compatible for use with condoms. The lube will not dry up on you during activity, but easily washes away with soap and water. There are three sizes available: Small (2.5oz), Medium (4.9oz) and Large (8.5oz).
