    3. Pack The Product Securely

    Pack your product securely and make sure you place the returns form in the package.

    - Allow your lava lamp cool for at least 24 hours before packing it (if you have turned it on to see the colour).

    - Use as much as possible of the original packaging.

    - If parts of the internal packaging are damaged use appropriate packing materials such as strong cardboard and bubble-wrap to ensure the product arrives in a like-new condition.

    - Protect the plug pins with suitable material such as bubble wrap or newspaper.

    - Protective material should be wrapped around the base and cap to protect them from scratching, the lead can then be wrapped around the outside of the base.

    - Remember lava lamps are made of glass so must be packed very securely. 

    NB. All returns must arrive at Mathmos in the condition in which they were received; unused, undamaged and returned in the original packaging. If the product is not returned to us in fully resalable condition, we reserve the right to refuse or reduce the refund on the item.

    4. Send Your Product Back

    Mathmos does not accept responsibility for goods which are lost or damaged in transit, so we recommend you pack your items securely and keep your proof of postage.

    You can use either;

    Post Office - Affix the address label at the bottom of the Returns Advice Form to the outside of your package, take it to the Post Office and send to us. This is not a pre-paid label so you will need to pay return postage. Please retain your proof of postage.


    Collect Plus (UK only) - Affix the address label to the outside of the package then return the products to us using Collect Plus by clicking here. This link will allow you to pay £6.29 by PayPal or card (for a 2-5kg parcel) and print a PDF label to attach to the outside of the package. When it's dropped off at any of the Collect+ locations a receipt will be issued as proof-of-postage and you will be given a tracking code to follow it online.
