Everything stored in a small cloth bag, a little "light" but it keeps them well sorted shelter in the book bag, that's all we ask. Headings are written on each needle (size US and Europe), it is convenient but I do not know if they will withstand the wear.
Bamboo is soft, no rough edges, wool glides well. For now it is very pleasant to use, and I do not regret my purchase.
(I had already invested in bamboo hooks kit, the same manufacturer, and I am delighted too)
