The sticker is designed to be placed on front of the case. Everything from the wording on the label that says "Original Floss," to the phony Oral O branding wouldn't cause anyone to give the container a second look. In fact, you could probably leave the container in your desk at work and not worry about your AirPods getting stolen. That is, unless you have a co-worker who needs to floss!
Considering that the AirPods cost $159 for the set, paying $4.99 for the sticker seems like a bargain. If interested in turning your valuable AirPods into cheap floss, click on the sourcelink.
