At some point, these pink erasers were dubbed “Pink Pearl,” after Faber’s selection of Pearl pencils. (The name was trademarked in 1937, although it was used as early as 1910.) Quickly, pink erasers had become ubiquitous. The Blackwing 602, which has been lauded as “the best pencil ever made,” featured a pink eraser when it was originally launched in the 1930s.
“As they gained notoriety, pink pumice erasers became more popular,” says Weaver. “These days they’re usually colored to be pink because that’s the color we’ve come to expect them to be, which can be credited to the trusty Pink Pearl.”
Pink Pearls are still produced today, under the Paper Mate brand. They’re now made of synthetic rubber, rather than natural rubber and pumice, says Weaver. (When reached for comment, Newell Brands Office Products—owner of Paper Mate—said any information on the composition of the Pink Pearl is proprietary.)
