Lost, delayed or damaged
If tracking has not moved for five business days, or a parcel arrives damaged,
write to [email protected] with your
order number and photographs where relevant. We will open a carrier claim and
resolve it with you — you will not be asked to negotiate with the courier.
Thirty days, unused and in its original packaging, no explanation required.
The window
You have 30 calendar days from the delivery date to return an
item. Requests started after that window can still be reviewed case by case, but
we cannot guarantee approval.
Condition
Items must come back unworn, unwashed and in their original packaging, with any
tags attached. For hygiene reasons the following cannot be returned once opened
or used:
- Personal care tools that contact the skin or eyes (for example heated lash
curlers and facial tools); - Socks, hosiery and hair accessories removed from their sealed packaging;
- Face coverings and earrings, for hygiene reasons;
- Items marked final sale at the time of purchase.
How to start a return
- Email [email protected] with your
order number and a one-line description of the problem. - We reply within one business day with a return address and a reference
number. Please do not ship anything before you have that reference. - Send the parcel back with the reference in or on the package. Keep the
carrier receipt until your refund lands.
Refunds
Once the returned item reaches us and passes inspection — usually within three
business days of arrival — we refund the price you paid to the original payment
method. Bank processing adds a further 5–10 business days depending on your
issuer. Original shipping charges are refunded only where the item was faulty or
we sent the wrong product.
Exchanges
We do not hold stock for exchanges. Place a new order for the item you want and
return the original for a refund — it is faster than a swap, and the returning
parcel is tracked the whole way.
Faulty or incorrect items
If something arrives damaged, defective, or is not what you ordered, email us
with photographs within 7 days of delivery. We cover return postage in full and
send the correct item at our cost.

Green S90 looks sharper in person than online.
Paired the S90 with my tablet straight out of the case, no fuss, connection was instant. But the white finish shows smudges fast, and shipping took almost two weeks. Still, for twenty bucks the sound is better than I expected for podcasts.
Bought these two months ago for treadmill sessions. The S90 stays in, tap to pause is quick, and battery holds most of the week. Only gripe is the touch controls sometimes trigger when I adjust the fit. Shipping took a while and the box was plain, but no regrets for what I paid.
