Please note: branding/barcodes may appear on parts of the cardboard box. Images are for reference purposes only and there may be slight variances to the product supplied.

Please note: these boxes are manufactured with a potential 10mm tolerance either way and this would need to be taken into consideration when purchasing. A sample service is available for you to test our products before purchase if this is perceived to be a potential issue.

DISCLAIMER: Remember, we are printing your artwork or logo onto a pre-manufactured product on an uneven surface in full colour which is an extremely difficult and challenging process. Whilst every care will be taken to give you the best results, there may be some slight imperfections or very slight colour variances. This would be more prominent if printing on brown or manila materials. Also, for best results please avoid large areas of block colour as this can give inconsistent print quality. If you're unsure, we suggest you order a single printed sample which should be used as a guide, as no refunds will be given for personalised products with slight imperfections or colour variances and incorrect sized products. Please note, we cannot guarantee to meet exact specific colour pantones. Finally, we reserve the right to request customers to amend artwork / creative and / or cancel and refund your order if we feel that we cannot guarantee a consistent acceptable level of quality.

Due to manufacturer tolerances, actual item dimensions may vary by 10–20mm. If precise sizing is important for your project, we strongly recommend requesting a sample before placing your order.

Because we use an on-demand, instant digital full-colour print system, we’re able to offer some of the lowest minimum order quantities in the UK - perfect for small runs or custom projects.

Please note: a one-time low-volume set-up fee of £49.95 applies to any order under £100. This is added automatically at checkout, but it won’t apply to repeat orders of the same product as long as the artwork remains unchanged.

All of our products are manufactured and dispatched right here in our own UK warehouse, which means we can offer some of the fastest turnaround times in the country. And because everything is produced in the UK (unlike many other providers), you’ll never have to worry about customs delays or surprise charges. Delivery is calculated at checkout based on order value - free over £70. All orders are shipped flat-packed for maximum efficiency.

100% Risk-Free Satisfaction Guarantee - We want you to feel totally confident when ordering with us. Before full production starts, you’ll get a proof (by app or email) and can make as many changes as you need until you’re completely happy. If you’d like to check our quality first, you can order a sample directly from the product page. Proofs aren’t provided with samples since they’re just for testing print and quality, but when you place your full order, you’ll be able to make amendments then. The cost of your sample will be refunded against your first full order*, and if you’re not happy with the quality, we’ll refund you in full.

*Sample refunds can’t be combined with other discounts or promotions.
