Sealable Plastic Badge Holder

The past two jobs I've worked at require badges (save the jokes, please) for identification.

Stock plastic badge holders provided with the badge open at the top to allow the RFID card to slide in. The unsealable opening at the top eventually lets in dust, dirt, and liquids. The badge ends up looking beat up after a year or two. Replacing the plastic holder helps, but it's a hassle.

It turns out there's a simple solution--purchase a pack of sealable badge holders from an office-supply store. For example, Office Depot, or intuitively enough, badgeholder.com.
