Review on MoKo Protective Silicone Anti Lost Backpacks by Robert Aan

These keychains are great for attaching AirTag to your keys. They are tight enough to hold the AirTag but are definitely looser than leather holders due to the materials used. I took off a star because they don't feel any more secure than a leather tag and I got a leather tag instead. 4 stars. EDIT 10/23/21: The silicone on the tags has become even less sticky over time and my tags have fallen out of the case a few times. They can still work in a pinch if you just want to keep them in a case in your purse, or maybe if you have a way to tighten them (I've seen some others with rubber bands for example), but otherwise use as a keychain instead I would choose a plastic or leather case for this.
