MUJI Pen Case for easy purse swapping

This is a rec within a rec because this isn't for pens (maybe one pen). This about consolidating essentials so I can switch bags easily and not forget the following (YES IT ALL FITS):

-Tide pen

-Lip product

-Gaviscon tubes (Italian food gives me instant reflux)

-Hand sanitiser for long days out

-Mini Koh-i-Noor hair brush

-pen or pencil
