These ties are great quality:
durable plastic, not too thin or thick, can easily be sewed by sewing machine (I'm using these ties for face mask nose wires);
the wire metal and gauge are also well suited for my purposes, having no sign of metal fatigue with multiple bendings.
Of course, they'd be perfect for bag closures.
