r/Packaging

we're getting custom packaging made for a new product and i'm realizing i have no idea how people properly check this stuff before approving it lol. the dieline looks fine on my screen, but i'm mostly worried about placement once the box is actually folded. like whether the logo sits where i expect, text ends up too close to an edge/fold, etc.

do you normally get a physical sample first or is there a good way to preview the finished packaging before paying for a full run? trying to avoid learning this lesson after 1,000 boxes show up.
