Boneyard's new Skwert Lube Injector is designed to keep your lubricant where it belongs - between the cheeks, not in the sheets! Simply replace the cap of your current lubricant with either of the two sizes and Skwert away! Customize the tube length for your bottle or remove the tube when the bottle is upside down to Skwert every last drop lube where it belongs. Caps fit approximately 90% of all lubricant bottles on the market.
