Happy April Fool's. You can buy these cookies and use them to prank your friends.
I was at a drug store in Tenmonkan, and I noticed the package of green tea Oreos on sale for 169 yen ($1.50 USD). Usually, these bags are 200 yen. I didn't bother taking a picture of the cookies themselves, because they look just like on the package. The green tea flavor is pretty strong. They're not bad, but it's not something you'd want to eat every day in place of regular Oreos. Strictly recommended for their novelty value.
