I'm a huge fan of acrylic boxes as I do think they look minimalistic and chic at the same time. They add that little something without being over the top and they are also very useful for those who have a lot of stationery they need nearby.
As the drawers are by my desk, I try and fill them with things I will use on a regular basis. The clear acrylic material means that I can see exactly what each drawer's contents are but it also means I can't just stuff it full with no regard for how it looks.
In the top drawer, I have some Avery note tabs, Post-it sticky flags, Rilakkuma sticky flags, some A6 note pages, Martha Stewart x Avery x Staples post-it notes and a few Iconic double-ended pens.
The middle drawer holds some more sticky notes and sticky flags, a pocket highlighter, a seemingly dirty cable tie and a few pens (a Uni-ball rollerball, Pilot Frixion Clicker and a pen for my transparent sticky notes).
Finally, the bottom drawer holds some more sticky flags and sticky notes, a roller tip-ex, an eraser and some Midori duck paper clips.
The contents in each drawer do seem quite random and I'm in the process of trying to organise them in a better way, whilst still fitting everything in so that it doesn't look too messy. It's almost like a real-life jigsaw puzzle!
