i seem to have a easier time with the boxcar. its ironic that most people say that the pinch has more control i cant control sniffing i either get none in or way back in the throat lol.i do have a question though which is better to use in public box car or pinch? the boxcar is pretty messy. although i do wind that if i cover my whole thumbnail i can barely feel it kin my nose i get surprised sometimes and think that i didnt sniff hard enough and ill find that i go most og it in my nose. the othr nostril is more tricky and generally which do you think is better for menthols? boxcar or pinch? the only thingg that j dont like about the box car ks that it takes longer and gets pretty dirty on one hand what are the benefits for both of them?
