They are very easy to make up, and they look great. Best of all, they go as a large letter, and the postage costs for one t-shirt, with a paper wrapping inside the box, are either Β£1.30 or Β£1.74 first class (at the time of writing August, 2017). Thanks! ### ⭐⭐ Poor Quality. *by T***N on 20 July 2018* Boxes are of a poor quality. Most PIP boxes will hold shape when folded without the need for tape etc. These do not. I will not be buying again, and disappointed that I bought so many. ## Frequently Bought Together - Crystal Mailing 50 x C4 A4 SIZE BOX 240x345x22mm RM LARGE LETTER CARDBOARD SHIPPING PIP BOXES - Generic 50 x C5 A5 PIP Box Shipping Mail Postal Large Letter Boxes - Size: 235x165x22mm Sold by MEG4TEC --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/53473356-crystal-mailing-50-x-c4-a4-size-box-240x345x22mm-rm](https://www.desertcart.gr/products/53473356-crystal-mailing-50-x-c4-a4-size-box-240x345x22mm-rm) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-12*
