We recently discovered these quirky retro boxes and love them. The simplistic design is made more interesting because of the façade, which gives a sense of nostalgia and familiarity.
The fun aspect of these boxes is the DIY aspect. Simple slotting together provides a quick set up with out leaving the user bored and frustrated. The perfect balance between time taken to assemble and the difficulty mean that any family member can use these. Perfect!
Here is a quick video of an assembly we did in our office. The box proved very popular and we assembled it many times.
