those pickles are a joke. it's just foam dust in there
Sure, if one has access to foam dust, one can put said foam dust into pantyhose and create their own pickle.... but it will be brown, so you'll have to come up with a different name..... lol.
I don't like using sawdust because you have to be careful what you're using--it's never uniform in "grain" size and mine's always mixed with something you shouldn't be breathing. ie black walnut (silica will cut your alveoli), wenge (sawdust is actually mostly tiny needles like fiberglass and it's poisonous), cedar (many people are highly allergic to the dust), etc..
