I have too many bags. Switching bags becomes a chore because I have to organise everything again and usually something gets lost in the process, my diary or a pen or lip gloss. So I got myself a bag organizer or bag caddy. Everything from keys, diary, camera, diary, shades, lip gloss goes into this caddy and I simply transfer this caddy to the new bag. Easy peasy.
Gin & Jacqie a homegrown brand has these in stock.
Online, I found other options that are not stocked here though. They are pursekets and come in 3 different sizes.
I like mine.
