The Photopack Snappy 2021 wasn't a stranger's collection. It was a visual map of a week he had lost, sent to him by a version of himself he no longer recognized.
There is a small convex mirror next to the lens for selfies. However, unlike the Instax Mini 11 (which has a dedicated selfie mode/close-up lens attachment), the Snappy 2021's close-focus limit is 1 meter. If you take a selfie at arm's length (30cm), you will get a blurry photo. You must use a selfie stick or extend your arm fully to push the subject distance to ~60cm.
