I bought this for my 11 year-old for taking both instruments to school. A pretty good quality double case for flute and piccolo. Usual Protec standard hard wearing material. My only gripes are that there is only a small amount of padding in the flute section and none at all in the piccolo part, making you rely on the hard cases of your instruments inside. The bag itself is oversized, bigger than standard flute and piccolo cases, so they do rattle around in there and the hard cases take the knocks. It could have provided a tighter fit.
Overall not a bad case, and certainly better than having to carry two separate ones around.
