Fits the Airtag well, fits in my wallet.
At first I was afraid the airtag would not fit in this, but it's slightly flexible and the airtag pops right in.  This is slightly thicker than I expected it to be having  a small lip on either side of the airtag, and I feel like it could be made slightly thinner.  Prior to getting this in the mail I just had the tag sitting in the inner pocket of the wallet... it worked but almost slid out a couple times when I got out my wallet and I was afraid sitting on the tag would ultimately break it, this solves that problem but adds the thickness of the airtaig (plus a tiny bit) to toe the entire width of the wallet.  Ultimately i'm happy with the purchase and it does exactly what I wanted it to.
