Regular test strips work, but nobody wants to pull out a clinical test card at the bar. That's why they stay in the bag.
One for every friend.
Most women share their stickers on the first night out. Grab a pack for the whole group and save.
Honest about what it does.
- Nightnail screens for GHB and ketamine. It does not detect extra alcohol or every possible substance.
- No reaction doesn't guarantee a drink is safe. If anything tastes, looks or feels off, don't drink it.
- Milky, very acidic or dark red drinks can affect the result. Test one at home first so you know the colors.
How do I use it?
Press a sticker onto a clean, dry nail. When you want to check a drink, briefly dip your fingertip so the sticker touches the drink, then take it out. If one half turns yellow-green, don't drink it.
What does it detect?
It screens for GHB and ketamine. It does not detect extra alcohol, benzodiazepines in every form or most other substances.
What should I do if it changes color?
Stop drinking immediately, tell a friend you trust and a member of staff, and keep the glass if you can. If you feel unwell, get medical help straight away and don't leave alone.
Will it stay on all night?
Yes. It's made to last a full night out, including hand washing. Apply it to a clean nail with no oil or cream and press it down firmly.
Does it work on gel and acrylic nails?
Yes. It sticks to natural nails, gel, acrylic and press-ons, and peels off without damaging your manicure.
Can I reuse a sticker?
No. Each sticker is single use. Use a fresh one for every new drink you want to check.
