The only negative is that the glue on the sticker to join it and make it a bib doesn't stick well and the baby pulls it off with one move... Otherwise, for one use outside the house, for example, it's incredibly convenient.. you do your job and throw it away!

They have been very convenient for meals outside the house, compared to taking along the silicone bib that I usually use - which, of course, needs to be washed after every meal. They are made of soft material and have adhesive on the neck and in front of the chest - it is not very strong and the baby easily removes it, but still provides some stability.
