According to RocketNews24, the new chips are made in partnership with Hokkaido-based chocolate manufacturer Royce, which in turn is known for making things like chocolate-covered chips and chocolate-covered popcorn as well as the more standard chocolate bar.
Also, this is not the first collaboration for the two companies: they've also put out chocolate-covered shrimp-flavored chips.
Calbee's new strawberry white chocolate-covered shrimp-flavor chips go for 713 yen (~$6.94 US) a box.
