备注	PWPW produces these test notes specifically to demonstrate and market their security substrate and printing capabilities to potential government clients — they are trade samples, not currency. The 2012 bee-themed piece was part of a broader push by PWPW to promote their proprietary polymer technology at a time when several central banks were actively reconsidering paper substrates. These notes were never intended for circulation and were distributed in limited quantities at industry events and to institutional contacts. The inclusion of a watermark on a polymer substrate is the technical point of interest here — simulating a watermark effect on plastic film requires a different optical approach than traditional laid paper, and demonstrating it convincingly is precisely the kind of proof-of-concept these notes exist to provide.
