Email is our only support channel. It gives both sides a written record of restock numbers, lot numbers and decisions, which is what a return or a recall depends on.
How fast we answer
| Subject | We answer within |
|---|---|
| A defect, a broken seal or a safety concern | 1 business day, ahead of everything else |
| A restock in progress | 1 business day |
| A return request | 2 business days, with the return authorisation |
| A studio verification request | 3 to 5 business days |
| Anything else | 3 business days |
Business days are Monday to Friday, excluding US federal holidays. A message received after 17:00 Eastern counts from the next business day.
What to include
- About a restock: the restock number from your confirmation email.
- About a material: the restock number, the lot number printed on the box, and photos of the box, the seal and the unit if something is wrong.
- About verification: the studio name and city given on the Verify page, sent from the studio email address.
- About your data: the studio email address the data is held under. The Privacy policy lists your rights.
If a material may have harmed someone, or a seal was found broken before use, start the subject line with URGENT. Those messages are read first.
Returns and parcels
Do not send anything back without a return authorisation. Returns go only to the address given in that authorisation, and a parcel that arrives without one cannot be matched to a restock. The Returns & recalls policy explains the steps.
