The keychain loop is too small for some rings or an airtag in my case. I've solved that with a smaller ring that holds onto the bigger one, which also works i suppose. Other than that, the case is lovely and my brother is very happy with it. I've ordered from Burga before and both times the item ordered was delivered well within the deadline and arrived in tact as well as in expected quality. A pleasure shopping here and when me or a friend needs a case, I'll definitely consider buying more stuff from up here.
