BOX USA 20x5x5 Long Corrugated Boxes - Long Mailers Pack of 25

Our review of the BOX USA 20 x 5 x 5 long corrugated boxes finds them best for anyone shipping or storing long, narrow items where a slim, reusable carton matters. The single biggest reason to buy is the lengthwise opening and compact flattened shipping that make them easy to store and quick to pack for small business mailings or hobbyist projects. These cartons are made from 200#/ECT-32 kraft corrugated, and that construction plus the narrow dimensions make them a practical choice when you need reliable, recyclable packaging without taking up much warehouse space.

Key Features

• Lengthwise opening: Wide openings along the length make packing long items like rods, picture frames or rolled documents faster and reduce fidgeting with awkward ends.
• Narrow profile: The 20L x 5W x 5H size is optimized for long, slender items that would be loose in standard boxes, helping protect contents and reduce filler material.
• 200#/ECT-32 corrugated: The kraft corrugated construction balances weight and strength for routine shipping and stacking in small wholesale bundles.
• Ships flat: Bundled cartons ship flat to save storage space and lower incoming freight costs, useful for businesses receiving bulk cartons.
• Reusable and recyclable: The cartons can be reused for multiple shipments and are recyclable, which helps reduce packaging waste.

Who It's For

The BOX USA 20x5x5 long boxes are ideal for small businesses, mail order sellers and crafters who regularly ship long, narrow goods like posters, tools, samples, or components and need an efficient, space-saving carton. They work well when a slim footprint matters, and bulk packs of 25 provide a steady supply without frequent reorders.

These boxes may not be the best choice for very heavy or irregularly shaped items that need deep cushioning, or for users who need perfectly aligned, precision-folded corners for cosmetic presentation. If closing and corner alignment are critical, consider alternative packaging styles designed for tight corner fit.
