The product appears to be of good quality but the extra narrow size/caliber is no different from the "narrow" size ie. They don't fit better between the teeth if you have very closely spaced teeth. If you are concerned about recycling, you should be aware that there is a lot of plastic used in food packaging and manufacturing. Don't think it can be recycled.
