Sure, for some people, a yoghurt-based drink doesn’t sound particularly appealing, especially when paired with a name that sounds like bovine urine.But Calpis remains popular in Japan and has been for over 100 years, with the company constantly coming up with fresh and creative collaborations.This year, Calpis has released limited edition summer Calpis Water bottles, with three unique designs all featuring charming illustrations of high school kids and their after-school life. But there’s also a mysterious instruction: “Once you finish the drink, a new illustration will appear.” What is this, Alice in Wonderland?

The person responsible for the beautiful drawings on the bottles is artist Rei Kato, who posted the full illustrations on their Twitter account.
