Query: Sturdy, Compact Badge Holder

My company issued me a RFID door key, which for convenience sake I keep on a spring loaded string off my belt. I broke a key recently and its replacement has no cut out for attaching strings, so I needed a sleeve. The sleeves I found at Staples were much bigger than my card key, so I went to Amazon and found this item. It's only a bit bigger than my card key, so it satisfies my requirements. It seems sturdy enough and has no real downside, no odor or sharp edges. I guess it could have been an eighth of an inch narrower, but that is just a quibble. The RFID works through it, so buy with confidence.[Update: the holder lasted about 3 months before starting to tear. Lucky, I have 11 more to go.]
