A parallel universe is the ink brand. Growing up Bril was the "cheap" and popular brand. But the best one was Chelpark.
Oh boy, this brought back memories. Turquoise Blue + Chelpark was nirvana level experience for me. Whoever (mostly teachers) noticed that shade of blue would get immediately confused. Is it blue? Is it Green? It would lead to a good discussion!
Of course, Bril was the workhorse.
Chelpark Turquoise and Bril Royal blue were my favorites too. They both looked brilliant on paper!
