About Us

Steel Harbor is an original collectible-card press. We design, print, and pack Signal Series — illustrated cards built around a fictional Harbor Circuit of maps, plates, and night-span inserts.

We are not a marketplace for other companies' products, and we are not affiliated with any sports league, character franchise, or other card publisher. If a card has a name, a number, or a harbor on it, it is ours.

Why we make boxes

The hobby is the open: a sealed pack, a checklist you can finish, a numbered plate that might be in the next wrapper. We write what is in each product before you buy. We do not sell guaranteed dollar values, guaranteed grades, or investment claims.
