Pinky Proof Drink Testing Sticker

Dip a clean finger or a straw into your drink and transfer a single drop onto each test pad on the sticker. Don't dip the sticker into your glass. Watch the pads for 10 to 30 seconds — a clear colour change means a positive result.

It screens for GHB and ketamine, and reacts to some related amine-based compounds. That's it.

It does not detect extra alcohol, benzodiazepines in every form, or most other substances. Being honest about that matters more to us than a longer list.

No, and no strip of this kind does. Adding extra spirits to a drink is the most common form of spiking and it's chemically invisible to these tests. Keep your drink with you and pay attention to how you feel — that's still the thing that protects you most.

It means those specific substances weren't detected, at detectable levels, in the drop you tested. It does not mean your drink is safe. Something could be present below the detection threshold, or be a substance this test doesn't cover.

If anything feels off — the taste, your drink's appearance, how you feel — don't drink it, whatever the test says.

Yes, and this is important. Milk-based drinks like milk or cream liqueurs will show a positive GHB result even when nothing is there. Very acidic drinks like bitter lemon or lime cordial can hide GHB completely and give a false negative. Red wine and dark berry drinks stain the pads and interfere with both tests.

On those drinks, the result can't be trusted in either direction.

Stop drinking it immediately. Tell a friend you trust and a member of staff — bar teams are trained for this. Keep the glass if you can, since it may be needed later. If you feel unwell at any point, get medical help straight away and don't leave on your own.

No. Each sticker is single use. Once a pad has been wet it won't give a reliable result again, so apply a fresh one if you want to test another drink.

It's designed to last a full night out, including hand washing. Apply it to a clean, dry nail — no oil or hand cream on the surface — and press it down firmly for a few seconds.

Yes. It sticks to natural nails, gel, acrylic and press-ons. On a very glossy top coat it may lift slightly sooner, so press it down well when you apply it.

No. Peel it off slowly from one edge. It leaves no residue and won't lift polish or gel underneath.

The colour change is visible in low light, but it's worth doing one at home first so you know exactly what you're looking for. If you can't read it clearly, step somewhere brighter or use your phone torch.

Each pack contains multiple single-use stickers. Most people keep a few in a bag or purse so there's always one spare for a friend.

Keep them sealed, dry and out of direct sunlight and heat. Don't leave them loose at the bottom of a bag where they can get damp — moisture affects the pads before you ever use them.

Yes. Check the date printed on the pack and replace them once it passes — the reagents lose sensitivity over time and an expired test can't be relied on.

No. It's a consumer screening indicator, not a diagnostic or forensic device. It can't prove a drink was spiked and it can't prove it wasn't. If you believe you've been spiked, seek medical attention and report it — a hospital or the police can carry out proper testing.

Unopened packs can be returned within 30 days. For hygiene and safety reasons we can't accept opened packs back.
