The letters come on pieces of paper folded up and nestled inside the capsules, and while some are printed with a hand-written font, others actually are written by hand.
But who’s actually putting pen to paper? That was the question put to Capsule Corporation CEO Hideaki Eto by magazine Nikkan Spa, and at the risk of shattering the illusion, he revealed that the letters are not, in fact, written by teenage girls. “They’re generally written by women in their 20s, 30s, or 40s” Eto explained. Most of the time, it’s one or two women writing the expressive, brightly colored characters, but when things get busy, they bring in five or six part-timers to help with the extra workload.
