Oh, I love when people think about the packaging first. A matte finish feels like a quiet invitation; it absorbs light, so the colors on the cover are more muted and the artwork looks almost like a painting. It also hides fingerprints, so you can touch it for months without it looking greasy. A glossy sleeve, on the other hand, gives everything a bit of shine, almost like a glossy book cover. It can make the colors pop, but it also draws the eye and feels less like a quiet artifact. For a Star Wars box set I’d lean toward matte if you want the set to feel like a piece of art that stays fresh to the touch, but if you’re after a bit of flash to show off the new trilogy’s bold colors, glossy might be the way to go. The choice is really about whether you want the set to whisper or shout.
