It is really inconvenient when a presentation file is difficult to hold. It is awkward to carry and can even fall out of your hands. Avoid this by using webbing.
Webbing, also known as a carrying band, is a flat woven band made of PP. It is often used as a handle or fastening. Carrying bands are ideal for carrying a sample book or presentation case.
The advantage of webbing is that it is easy to hold and comfortable to wear as a shoulder strap.
