The needles are in different bags that are combined in a resealable pouch: which stows neatly. Very convenient.
There is a sewing needle in each bag.
I used a few sizes (4 sizes).
One of the needles is "broken": the thread is picked up without serious deterioration. Nothing so a small drop of superglue3 can not repair.
Apart from this detail, nothing to say: the quality seems good.
This is the first time I use circular needles so I can not give a technical opinion.
