Why Vesper exists

Built for the nights you look forward to.

Test strips live at the bottom of a bag. Test cups are a scene. We wanted something that is simply on you, that looks like part of the outfit, and that you can use mid-sentence without anyone noticing.

So we put the chemistry on a nail sticker. A clear film with a rose-gold crescent that turns red if GHB or ketamine is detected. One dip, thirty seconds, a colour you can read by phone light. Every pouch carries a batch number and an expiry date, and we say plainly what it does and does not detect.

Good to know

Questions, answered honestly.

Read the full FAQ
What does Vesper test for?

Each sticker reacts to GHB and ketamine, the two most common drink-spiking substances. It does not detect added alcohol or other substances, and a negative result does not mean a drink is safe. Trust your instincts first.

How do I use it?

Wear the sticker on a nail. Dip that nail into your drink for 1–2 seconds, wait up to 30 seconds, and check: the sticker turns red if GHB or ketamine is detected. Try one at home first so you know what to look for in a dark bar.

Does it work over gel or acrylic nails?

Yes. The sticker sits on top of any finish — natural, polish, gel or acrylic — and peels off cleanly at the end of the night.

How many stickers are in a pack?

A pouch holds 10 test stickers. Bundles come as 20 or 40 stickers, and the gift set as one pouch of 10 in a gift box.

How long do they last and how do I store them?

Every pouch carries a batch number and an expiry date, typically 12 months from production. Keep the pouch sealed, dry and out of direct sunlight.
