From a practical point of view, it can really be used to hang things, especially some universal padlocks/buckles.

But hanging decorative pendants is not the main reason for the design of decorative parts. These decorative pieces/corner pieces were originally designed to make the backpack stronger and prolong its service life.

Lash Tab was originally used to fix bandage joints and bottom seams.

This is common in some old-fashioned backpacks. Usually, decorative pieces will be sewn on the corner/bottom of the backpack that is easy to wear, or on the top of the bandage and backpack fabric for secondary fixation.

It is difficult to find such a pure and practical decorative piece in bandages or bottom seams now. Moreover, because of the rise of retro style, decorative pieces have gradually been moved from a symbolic seam to a more conspicuous position, from a practical corner protector to a fashionable symbol, which is more beautiful and personalized.
