Overall rating: 4.9 / 5 from 2182 reviews.
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!
