「塑膠筆唯一的價值就在於其設計 [...] 這設計集合了來自藝術和科學的構想，而這些構想相互交織
"The only thing that gives plastic pens any value is their design [...] This design represents a coming together of great ideas, which—being derived from art and science—have cross-fertilized and creatively complemented one another. Yet this is a design we don’t even notice, so such pens tend to be given away free."
- Vilèm Flusser ／The Shape of Things
