Considering a printed sample?

We offer an optional printed sample so you can confirm colour quality, print sharpness and suitability before ordering in larger quantities. When you proceed with a full order of the same design, we will refund the cost of the sample.

Please note: Minor branding or barcodes may appear on the small parcel mailer box. Images shown are for guidance only and the supplied product may differ slightly.

Due to manufacturing tolerances, actual item dimensions may vary by 10–20mm. If sizing accuracy is essential, we recommend ordering a sample before placing a larger order.

Authentic Product Photography

All images displayed on Parcelsend UK represent genuine printed jobs we have produced. No visuals on this page are created or enhanced using AI - every photograph is taken from real customer orders to give you an honest representation of print quality and finish.

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.
