Custom Box Making in Bonney Lake, WA

If It Needs a Box, We Can Build It.

Not everything ships in a standard box — and that's fine, because we don't just sell boxes, we build them.

That antique. That piece of equipment. That thing you're nervous about shipping because you know a standard box won't do it justice. Bring it to us. Sound Postal custom-builds corrugated boxes to fit your items' exact dimensions, and we'll pack everything ourselves so you can hand it off and stop worrying.

We've built boxes for all shapes, sizes, and levels of "please don't break this" — and we take every one seriously.
