Yes, like here, the Japanese caption did not give the formal name for this lint roller. It just said "この世の便利道具". Actually, now that I look at it, VIZ fumbled this gag. It says この世 as in "this world", so it actually means "A Handy Real life Item", since この世 refers to the normal world while あの世 means "afterlife" or "the other world".

It literally is a lint roller.
