Attack on Titan: Colossal Edition 4 is an oversized collection of volumes 16-20 of the Attack on Titan manga series. Weighing in at a massive 944 pages and a 7\' by 10 1/2\' trim, Colossal Edition 4, like its predecessor last year, contains the same material as the original volumes, but bigger and on higher-quality paper.
