The first impression

Packaging and contents

Here we take a closer look at packaging. Sustainability is becoming an increasingly important factor. In addition, adequate protection of the product must of course also be guaranteed. Are the contents of the packaging complete and does the manufacturer make it as easy as possible for me to use the product straight away?

The cold pack from VonBueren makes a very good first impression as soon as it is unpacked. It is delivered in a classic shipping box that protects the product securely. The compact packaging ensures that the cool pack arrives undamaged. Unfortunately, the use of non-recyclable materials in the packaging is a small minus point in terms of sustainability. However, the contents of the pack are complete and in perfect condition, which underlines the quality of the product. Although there are no instructions for use, the cool pack is easy to use thanks to its intuitive handling.
