Sized for Bulky Parcels, Not Letters or Small Packages
This is an oversized mailing box for items that outgrow a standard mailer or bubble mailer: apparel bundles, home goods, multi-item orders, or bulky single products. Where our Bespoke Mailing Boxes cover custom-branded mailers at any size, this listing focuses specifically on the larger end of the size range.
Popular Use Cases
- Bulky e-commerce orders: Multi-item or large single-item orders that need extra internal volume.
- Apparel and home goods shipping: Bedding, bulky clothing bundles, and similar soft goods shipped by mail.
- Return and exchange shipping: Oversized boxes that give customers room to repack returns securely.
Sizes and Closure Options
Sizes typically run from 18x14x8 up to 24x18x12 inches. Self-locking tuck flaps allow tape-free assembly for fast fulfillment lines, while a taped closure option adds extra security for heavier contents or longer transit routes.
