It looks like you're referring to a Twix Chocolate Pouch Miniatures in a 220g size.

Twix Miniatures are bite-sized versions of the classic Twix chocolate bars, which consist of a layer of crunchy biscuit (cookie), topped with caramel, and coated in milk chocolate. The miniatures are perfect for snacking, sharing, or enjoying a small treat without having to commit to a full-sized bar.

The 220g pouch size is typically a larger, family-sized package or a party bag that would contain multiple mini Twix bars. These are popular for parties, candy bowls, or as a sweet snack on-the-go.
