Panini Comics

Panini Comics is an Italian comic book publisher. A division of Panini Group, best known for their collectible stickers, it is headquartered in Modena, Italy.[1] The company publishes comic books in Argentina, Brazil, Chile, France, Germany, Hungary, Italy, Portugal, Spain and the United Kingdom, as well as manga in several non-English-speaking countries through the Planet Manga publishing division.

In the United Kingdom, Panini Comics prints its Collectors' Edition (CE) line, which consists of reprints of Marvel US Comics. These are usually 76 pages long (with the occasional 100 page special), and the current cost of the comics is £3.50. A subscription offer is also available, and each comic is published every 28 days, with the exception of Astonishing Spider-Man which has been published fortnightly since volume 2.

They're the ones responsible for publishing the TMNT Magazine.
