Overlockers sew over the edges of fabric to resist fraying, such as around the edges of the internal part of front pockets, or internal seams.
I would have thought a flatbed personally as rear pockets are usually sewn on flat.
Yeah that definitely doesn't want to be overlocked.
Unless the manufacturer will replace them, just a 'quick stitch' type place should be able to fix that in a few minutes.
