Vepery, I reflect and try to understand))

My daughter bought herself a wipe, I do not even know how to treat it. In general, the thing is certainly interesting, I tried to soar myself)) I even liked it, of course I let the rings go and I did not learn how to be a daughter, but it was still funny))

Mixtures were tried different, with nicotine and without.
About nicotine is clear, of course it's harmful, but I had a question if the composition without nicotine contains glycerin and propylene glycol, is it harmful?
