I hate training things on the face, ugh. Anyways, mostly works. The nose and the vertical strap are a struggle. Recommended for advanced prompters. Obviously if there is a hair bias it'll stop the forehead strap at the hairline.

Str 0.7 to 1, leans very photo, was a small dataset

(black latex gag, covered mouth, gagged, g4g, nose), o-ring, gag_harness

if you're having trouble with the forehead strap, you can try forehead strap
