New Jersey based N-Star Import and Export LLC., has introduced "Cocofun Green Tea Wafers" into the US and Canada.
I imagine this is something you might see in those japanese and korean food shops. I know love cream filled wafers! My mom used to buy them when I was a kid, and I could scarf through 'em in minutes.
I guess green tea flavored filling would be a hit here, since it seems to be getting into everything else.
These wafers are said to be made in South Korea, and are low in sugar. They're presented in a 2-count foil wrapper, and sold in a 6-count, 90g box. The package copy identifies them as "Delicious and nutritious crispy wafers with green tea & mulberry leaves."
