We didn’t set out to start a tissue company. In fact, noissue was born out of necessity. We were looking at packaging for a previous endeavour, and couldn’t find exactly what we needed. Since we’re not much for sitting about and making do, we decided to fill that gap in the market. Noissue was started with a single intention: to make premium custom tissue attainable for brands at any stage of business. Our company is based on a few core beliefs. At the heart of those beliefs is a focus on customer satisfaction. Our customers have helped shape what noissue is today. To be frank, it’s not really about us —it’s more about what you need to help your business be the best it can be. We believe that sustainable packaging doesn't have to be unattainable. You can be environmentally conscious and responsible while creating a premium product for your customers to enjoy, and we can help you do it. We chose the name ‘noissue’ because we’re committed to eliminating the unnecessary issues that can crop up with custom production. Our goal is to make packaging easy, so you can get back to what’s most important: your business.
