Doesn't look to good when using it as a gift box. Review: Boxes arrived damaged/unusable twice! - Boxes themselves are sturdy. However, using them for wedding welcome boxes means they can’t be warped, dirty, dented, torn and unusable. They’re packed, in assembled of course, in group of 50 and zip tied together. The zip tie ripped all the edges it touched and then just as bad, they’re wrapped like a 5 year old did it, with clear cellophane so they’re not protected at all! So you get them filthy dirty! Sent first batch back and tried ordering again. Same issues the second time! If you need undamaged, clean boxes, don’t order these!!!!! ## Features - Feature protective side flaps and front outside tuck closure. - Maximum protection for your most important documents. - Manufactured from strong 200#/ECT32-B white corrugated. - Assembles in seconds without tape, glue or staples. - Proudly made in the USA! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00BT3MTII | | Best Sellers Rank | #170,784 in Office Products ( See Top 100 in Office Products ) #977 in Box Mailers | | Brand | BOX USA | | Breaking Strength | 65 Pounds | | Color | White | | Date First Available | March 12, 2013 | | Department | Unisex-Adult | | Item Weight | 10.2 ounces | | Item model number | MFL16124 | | Manufacturer | BOX USA | | Material | ECT-32 Single Wall Corrugated | | Number of Boxes | 1 | | Product Dimensions | 16"L x 12"W x 4"H | ## Product Details - **Brand:** BOX USA - **Breaking Strength:** 65 Pounds - **Color:** White - **Item Weight:** 10.24 ounces - **Material:** ECT-32 Single Wall Corrugated - **Number of Boxes:** 1 - **Product Dimensions:** 16"L x 12"W x 4"H ## Images ![Box USA Shipping Boxes Medium 16"L x 12"W x 4"H 50-Pack - Corrugated Cardboard Box for Moving, Mailing, Packing, Packaging and Storage - Image 1](https://m.media-amazon.com/images/I/81fz6UA-kRL.jpg) ## Customer Reviews ### ⭐⭐ Perfect size box *by T***A on April 9, 2024* I didn't like that almost every edge of the box was bent. Especia6 the front. Doesn't look to good when using it as a gift box. ### ⭐ Boxes arrived damaged/unusable twice! *by L***A on September 9, 2022* Boxes themselves are sturdy. However, using them for wedding welcome boxes means they can’t be warped, dirty, dented, torn and unusable. They’re packed, in assembled of course, in group of 50 and zip tied together. The zip tie ripped all the edges it touched and then just as bad, they’re wrapped like a 5 year old did it, with clear cellophane so they’re not protected at all! So you get them filthy dirty! Sent first batch back and tried ordering again. Same issues the second time! If you need undamaged, clean boxes, don’t order these!!!!! ### ⭐ Boxes were ripped and damaged. Could not use 20 in Package due to damange *by K***E on November 12, 2021* I was excited for these boxes as they were easy to assemble but the quality was terrible. I couldn't use over half of the boxes due to ripping at the seams.
