Description
100-Piece Superflat White Mailing Box B21
Protect your shipments with the 100-piece Superflat White Mailing Box B21, an efficient and eco-conscious packaging solution designed for modern businesses. These boxes are crafted from quality kraft corrugated cardboard, incorporating over 50% recycled fiber to minimize environmental impact without compromising on durability.
- 310 x 220 x 16mm internal dimensions provide ample space for larger letter items while maintaining a sleek, flat profile.
- White outside, brown inside finish offers a clean, professional aesthetic that can be customized with branding.
- Self-locking die-cut folding design ensures quick assembly and a secure closure, saving time during packing.
- Lightweight construction helps reduce shipping costs, especially when sending items classified as large letters.

Compared to bulkier packaging or less rigid mailers, these Superflat boxes are engineered to slide through postal systems as large letters, significantly cutting down shipping expenses. Their compact, rigid design offers superior protection against bending and crushing, which is often a concern with standard envelopes or thinner cardboard options.

Boxes come flat which is great for saving space. Easy and quick to put together. Reasonably sturdy build.
220 x 145 x 35mm Tuck Front Heavy Duty Brown Mailing Box B392
ebPak have been my go-to place to buy shipping boxes for years and years. Good prices, wuality products. These boxes are no exception. They are lightweight yet sturdy and have a push-in tab to secure the top of the box down. It’s a very common size box (about A5) and fit loads of flat rate satchels from courier companies or logistical partners. Highly recommended! A+
I’ve been sending out vinyl in these packages for over a month now and all of them have arrived at their destination without any damage. They neatly fit 1 x LP but have the flexibility to fit a few which I find awesome. Highly recommended!

I am so satisfied for these gift boxses
Been using EBpack for many years, I get the bubble mailers for my small items and the poly mailers for my satchels. I get each size of satchel in a different colour, it makes it easy when I need to make the mailing labels.
Great size box for our small gifts!
