What to do now
Tests have found a harmful substance in Diamond Fresh naphthalene balls above the legal limit.
- Stop using it, and take it off children straight away.
- Wash your hands and any skin that has been in contact with it.

Why it matters. Limits on substances such as lead, cadmium, phthalates and formaldehyde exist because of their effects on health over time. Children are more exposed because they chew and handle products.

Get help urgently

This is general information based on NHS public guidance, not medical advice. In an emergency call 999. For urgent advice use NHS 111 (NHS 24 on 111 in Scotland) or, in Northern Ireland, your GP or out-of-hours service.
Getting your money back
Contact the seller through your order history and say that the product is the subject of an OPSS safety report. Keep screenshots of the listing and your order.
