This bio-hazard themed gas mask restrictor has a standard NATO40 thread so that it will fit the S10 or Russian Gas Masks. It features a 6mm diameter hole in the end that restricts the amount of air that can be drawn through it. This provides resistance when fitted to a gas mask and is ideal for breath play.

It has more defined grooves around its edge to aid grip and is made from ABS plastic. I can make them in four different combinations of colours.

I make these to order out of ABS, which is vapour smoothed so that they are smoother than other 3D-printed items, and the surfaces are sealed. The finish looks excellent, and the plastic is the same that is used in Lego.

This product is made to order, and each takes me three days to print, post-process and finish. So please allow for the extra time needed for me to dispatch this bespoke item to you.
