Kitkat is tapping into increasing sales of sharing formats by launching a box of smaller bite-sized packs.
Kitkat Senses contains 20 individually-wrapped chocolates, which come in hazelnut, double chocolate and salted caramel flavours.
The boxes will be available in a mixed box which contains all three flavours, as well as a hazelnut-only box.
Both have an RRP of £3.99 and have been available since the end of February.
The new launch is backed by a £7m campaign, which launches at the end of March and will run until June. It includes a new TV advert and sampling activity.
