Water-based lubes will work perfectly fine, but might not be ideal for larger toys as you’ll need to repeatedly reply. In which case we would recommend X-lube.  While silicone lube can be used with our toys, they will require a deep cleaning afterwards to remove all the lube. This is because the silicone lube is very good at sticking to our silicone toys and has a habit of sticking around unless a proper clean is carried out.
