From a post I made a while back:
" Here are caliper measurements of the thickness of OD pads and various ‘standard’ 19mm pads that I have on hand (without the paper backing):
One Drop slim pads: ~0.9 mm
CBC/YYF pads: ~1.1 mm
MYY pads: ~1.1 mm
Ilinx mousepads: ~1.0 mm
One Drop flow groove pad: ~1.8 mm"
The One drop slims are slightly thinner than “standard” slim pads. Other dimensions (inner and outer diameters) are pretty close across all of these. So much so that I trim down OD flow groove pads to make flush fitting OD “standard-type” pads. Discussed here.
@CaptainFoxxButt I have a bunch of OD slim pads on hand if you want some. I’ll warn you I’m in Canada though, still PM me if you’re interested. - I’d sell them at retail and likely mail them by letter post.
