The Nubby Plug is about 40mm overall, and that makes it one of the smallest pieces we have listed. It has a max diameter of 18mm, and the retention flange has a valley of 12mm; the bulb has a length of 24mm, and the flange expands to 21mm.
The #18 and #30 are the only silicone that we have available in pure translucent. The #00-50 and #10 base color are translucent white but can be mixed with all our standard color selections.
