Returns FAQs
What is your returns criteria?
14 days from date of receipt, or expected date of receipt on non-tracked
items.
How do I go about returning my order?
Please contact us
via our contact page with your order number. We will provide you with an RMA
number and return instructions, including your return deadline and whether a
freepost label applies to your order.
Do I need to contact you before returning my order?
Yes, to obtain an RMA number before sending anything back.
Does my item have to include its original packaging?
Yes, to qualify for our 14 day money-back guarantee. For faulty items, we
understand you may no longer have the original packaging.
Who pays for return postage?
If your item is faulty, damaged, or not as described, we cover reasonable
return postage, or provide a freepost label where available. If you are
