"Pocky (ポッキー Pokkī, Japanese pronunciation: [pokːiː]) /ˈpɒki/ is a Japanese snack food produced by Ezaki Glico. Pocky was first sold in 1966, and consists of chocolate-coated biscuit sticks. It was named after the Japanese onomatopoetic word pokkin (ポッキン?).

The original was followed by almond coatings in 1971, and strawberry coatings in 1977. Today, the product line includes variations as milk, mousse, green tea, honey, banana, cookies and cream, and coconut flavored coatings, and themed products such as "Decorer Pocky", with colorful decorative stripes in the coating, and "Men's Pocky", a dark (bittersweet) chocolate and "mature" version."
