Overview
Small shipping boxes — every corrugated size up to 12" on its longest side, from 4x4x4 cubes to shallow 12x9x3 cartons. Bundle quantities with the per-box price on every product page, shipped from 5 US regional warehouses.
How to choose: match the inside dimensions to your product with about 1/4" of play, then let weight pick the grade — standard ECT-32 covers most contents under 40 lb at these sizes. Small boxes are where dimensional weight rarely bites, so tighter is cheaper: a snugger box saves void fill and freight. See the size chart, or step up to medium sizes.
Frequently asked questions
What counts as a small shipping box?
In this range, nothing exceeds 12 inches on its longest side. That covers cube boxes from 4x4x4 to 12x12x12 and low-profile cartons for books, parts, and e-commerce staples — the sizes that ship at the lowest carrier rates.
What size box do I need for small products?
Measure your product, add roughly a quarter inch of play per side, and pick the closest inside dimension. Snug is better than roomy at this scale: less void fill, less dunnage, and lower dimensional weight on every parcel.
