What does "developed label" mean in the product description?

This term is usually encountered first on the front of the garment. The label bearing the name LOW CLASSIC is not hidden inside, but sits on the front as an accent^[1]. For auxiliary materials, "development" refers to determining the shape and specifications and creating them separately, rather than choosing and using off-the-shelf products available on the market.

Labels are not the sole place where the same term is applied. For zippers, instead of the tape where the teeth interlock, the slider held by hand itself is developed separately and used^[2]. When it comes to metal hardware, the method differs again, with the logo engraved into cantons and rivets^[3]. A canton refers to a metal button driven into thick fabrics like denim, and a rivet refers to small metal hardware pressed down to reinforce areas where stress concentrates, such as pocket openings. Both are originally components meant to fasten securely and withstand strain, so their surfaces are also used as places to engrave the name.

The location where the label is placed is not limited to the front, either. In some cases, the logo is placed at the center of the back of the neck as an accent^[4].

hmmm, while the front label and back neck logo are spots read first by someone facing or following the wearer, the names engraved on the slider and rivets are noticed only when zipping up or putting hands into pockets.
