The Chiaogoo Empty Interchangeable Needle Case is the empty version of the case that comes with the TWIST and SPIN interchangeable needle sets. It's a soft but heavy duty zipped cloth case.
It has 15 Labelled and 15 unlabeled pockets on the inside for your tips and will take both 5" and 4" tips. On the outside there is a zipped side pocket which can be used to store cables, stitch markers or other tools.
If you have tips escaping in all directions, then this is the case to keep them all under control.
