LetterBoxGifts has kick started its licensing programme, and will be looking to build further awareness at next week's Brand Licensing Europe.
The three-in-one product is a greeting card, gift box and mailer, with the firm believing it has opened up a new sales channel for licensees.
Belgian chocolate specialist Guylian has launched a selection of The World's Favourite Belgian Chocolates with five LetterBoxGifts cards, while Paladone UK has licensed the product for the novelty gift sector. Versions will appear in shops across the UK in early 2012.
Talks are also underway with several major confectionery brands, DVD and games companies.
LetterBoxGifts was shortlisted for Gift of the Year in 2010, and, more recently was voted as the Best New Idea by buyers at the National Convenience Show.
