People pay attention to the little details, whether consciously or not. So when you hand in that report or put together a manual, you should use these white Velobind strips. Whether you want the strip to disappear into your white covers or if you have a black cover and you want the spine to pop, these are perfect. And we have them in 1" (200 sheet capacity), 2" (500 sheet capacity), or 3" (750 sheet capacity). All have a length of 11" to accommodate standard letter size. And we carry both GBC and our own brand. These 11-pin hot knife Velobind strips are a great way to secure your documents and keep them looking clean and professionally minimal.
