Don’t overcompensate your packaging supplies.

One of the biggest packaging mistakes is choosing a bigger box than you need. 

A large box for a small product, not only affects the environment but could be costing your company thousands in order fulfilment value. 

You’ve probably experienced this form of bad packaging for yourself when the toothbrush you ordered arrived in a shipping box.SHEYN packaging designIt is not only wasteful but takes away from the product experience by having to unwrap all of that unnecessary packaging. 

We have two mailer boxes sizes that will perfectly complement your small products.

Ideal for jewellery, cosmetics or other small accessories, these small mailer boxes will add value to your product. 

The full-colour mailer is the perfect choice for your small box needs. The vibrant, colourful designs will stand out on the retail shelves or make an immediate impression upon delivery. 

If you’re after an eco-friendly look we have a variety of sustainable options available.
