An AirTag holder for your Stanley tumbler

Bottle Beacon is a stretchy strap with a pocket for your Apple AirTag. On a Stanley tumbler it wraps around the cup above where it narrows, right next to the handle. No glue, and nothing to wedge under the cup.

Leave your tumbler at work or in the car, and the Find My app shows you where it is.

How it fits your Stanley

  • Tested on a Stanley tumblerThe one with the handle, shown here.
  • Sits next to the handleAround the cup, above where it narrows, so it stays put.
  • Stretches to fitThe strap is 13 inches and stretches to about 25, so it moves to your other bottles too.
  • 15 colorsGive every cup in the house its own color.
  • Comes off in secondsHook-and-loop, no tools. Apple AirTag not included.

Stanley is a trademark of its owner. Bottle Beacon isn't affiliated with or endorsed by Stanley.

Why a strap, not a boot?

Boots and inserts hide an AirTag under the cup, but each one fits a single size. Bottle Beacon fits any size and moves with you to your next bottle.

The trade-off: you can see the AirTag.
