Read the width column and the collaboration explains itself. Only four entries — Aaron Eyes small at 32.5, Bog Hog small at 33, the Franky Villani Guest Egg at 33.5, and the two 34.5 mm eggs — sit in the range most riders already have trucks and tape cut for. The bulk of the run parks at 36.5 mm, and then there are the two outliers: the Mutator at 44 mm and the Swampzilla at 45 mm.
That is a deliberate scaling decision rather than a catalogue of standard blanks with new art on the bottom. The names carry it too — Swampzilla, Bog Hog, Space Egg, Eye Crusher, Mutator read as a shape family, not a graphic series, and the egg shapes come with their own guest model. Stinkefingaz has kept the concave language granular to match: low, medium and medium+, with six of the twelve shapes offered in two options, so the same outline can be had flatter or deeper.
The practical consequence of a 44 or 45 mm deck is geometric and worth stating plainly: standard fingerboard trucks are built around decks in the low 30s, so on these two the hanger and wheels tuck well inside the edge. The listing does not recommend a truck width, does not say whether wider hangers are expected, and says nothing about how either shape behaves on a ledge or in a slide. Anyone buying a 45 mm board is buying an experiment, and that is probably the point.
One more thing the listing leaves open: who did what. It names Fos as the artist and Stinkefingaz as the maker, but it does not break down who drew the graphics, who cut the shapes, or how the licensing with Heroin is structured.
