Angstrom Gravitas is a high viscosity silicone lube that utilizes micro-friction of two nano-scale compounds to achieve unparalleled levels of smoothness and controllability. Gravitas is designed to be super long lasting, and retain smoothness far longer than traditional unmodified silicones. This version comes in a syringe with a dispensing tip rather than a container with a separate applicator. Some people find this to be more convenient, but please keep in mind that it requires quite a bit of force to dispense.
