Mounted deep inside a case lining rather than in an easily accessible outer pocket, a holder like this lets an AirTag keep reporting a bag’s position for as long as other nearby phones are relaying its signal — which, in a busy airport, is precisely the environment where a crowdsourced-network tracker performs best.
A lock and a tracker in one body, with the best failure mode on this shelf — and a title that calls Apple's Bluetooth network GPS.

States the thing that matters most about a battery-powered lock: when the battery dies the lock still works by hand, and the battery is only needed for the Find My connection
A replaceable cell rather than a sealed rechargeable one, so the device outlives its first battery
The title says "GPS Tracker" and the bullet says "Locate your luggage via GPS with the help of the global Apple Find My network" — Find My is not GPS, it relays Bluetooth sightings from other people's phones
Best for: One object doing two jobs, where the lock has to keep working when the battery does not
The one set on this shelf that describes its own mechanism step by step — the clip, the zip, the roll and the one-way vent at the bottom.

Describes the whole mechanism: slide the clip along the double zipper until sealed, then roll from the opening down, forcing air out through a one-way vent at the bottom
Names the material, PA+PE, which four sets on this shelf do and three do not
Titled "No Vacuum Pump Or Air Extractor is Needed" and calls its own bags "vacuum storage bags" in three bullets
Best for: Understanding what you are buying before you buy it
