There is still something important about sending important papers the first time. In fact, the way you mail a contract, proposal, or academic award not only reflects but also speaks volumes about your business or brand. This means that using the right paper is very important. That's why C4 boxes are now something everyone needs. Easy? Sure. But they're also great at making sure your papers stay neat, professional, and whole.
So, what exactly is a C4 envelope?
In plain terms, a C4 envelope is made to hold A4-sized documents Size 9.1 × 12.8 inches without folding them. With its outer dimensions of 324mm x 229mm, there's enough room to slide in important sheets while keeping them flat and pristine. There are no creases, no damage, just clean, clear communication—exactly how it should be.
