Cute and perfect to help me with my new "minimalist" commitment. After multiple shoulder surgeries I needed to get the purse straps OFF my shoulders. This wristlet hangs on my wrist without slipping off and has enough room for my wallet, chapstick, hand sanitizer, air pods, a few pens, a protein bar, and one or two other random items. Looks small, holds a LOT! Withstands my everyday life of banging it around, spilling coffee on it, and generally putting it through a wringer. It still looks great!
