Yes we do ship to PO Boxes.

The country you are shipping Z Lab goods to may charge tax or duty on your shipment. How much is charged depends mainly on the value of the goods being imported and what type of goods they are. Every country has their own set of rules, regulations and taxes for importing.

If taxes or duties do apply to your country then it will be your responsibility to pay for these (and any import fees) to the local authorities and is not something Z Lab is involved with.

Some countries will allow you to choose to pay at the checkout or to pay upon delivery of the item(s). Your local customs office should be able to give you an estimate on the cost of import fees.


We have a 30-day money-back policy which means you have 30 days from the delivery date of your item(s) to request a refund.

Please let us know your order number and reason why you are returning the item(s) by contacting us at

Yes this is no problem. Please just return the item(s) to us following our returns process shown above and if they are approved, simply make a new purchase on the website.

In the event that the wrong product was sent to you, we will fix this issue by sending you the correct item, once we have received the wrong item back from you. Any costs incurred on your behalf for the return of the wrong item shall also be refunded by us once we have received the goods from you.

If the goods are lost or damaged in transit, please let us know within 15 days from the time your order was placed, so that we can make a claim against the carrier. We will offer you the choice of a replacement or a full refund.

If a customer decides to cancel or reject the delivery of their order or package together with the carrier without previously noticing us at, then we will not be responsible for the cost of the returned shipping package.

If a customer orders 5 or more items in one single order and decides to return all items, a penalty fee of 10% will be applied on the overall order value. This fee will be used to cover the logistics cost associated with the order such as handling, packing, shipping and receiving the returned order.


We accept all major payment methods including Visa, Mastercard, American Express, Paypal, Apple Pay, Google Pay, Shop Pay, Diners Club, Discover and UnionPay.

At this time we accept payment in GBP, USD and AUD. We hope to add more currencies in the future.

Please select a currency in the drop down box at the top right-hand side of the website.

Your payment may have been declined due to one of these reasons:

- we don't ship to your particular country.

- the card details have been inputted incorrectly at checkout (for example the long card number, the card expiry date or the security number on the back of the card).

- the card is out of date.

- your bank has blocked the payment.

Please check the above. If your bank has blocked the card then please speak to them about unblocking it as they will not tell us the reason for this. You could also try using another card or payment processor as an alternative way to pay.


We are aware that every action has a reaction, especially when you are a physical products company.

Sustainability therefore is at the heart of what we do and how we build our products. We will strive to increase our sustainable impact through innovation and implementing green technologies and processes.

Yes our packaging is either compostable or recyclable - more information on our packaging is available here.

We have also taken a minimal approach so the products are not needlessly wrapped in additional cellophane (or similar).
