Pros:
- easily assembled from a flat piece, bent into shape.
- stackable.
- helpful for keeping dust off cups long-term, for example, putting Christmas cups away for the season.
Cons:
- as you can see, they don't exactly seal well.
- material seems to gather dust easily.
- they dont take into account the cups with horns and ears.
- $20 CAD for 12 acrylic boxes is a little bit much. If more went into the design to make them more secure when stacking them (like notches to slide into, for example), then this price point would be a bit more understandable.
