But basically you can carry anything except offensive weapons/firearms/explosives. No restrictions on liquids or tweezers and scissors. You have to put your bags through an x-ray machine and walk through a metal detector after you check in.

Eurostar has specific security regulations regarding sharp objects that differ slightly from standard airline rules. Small scissors with blades less than 6cm (roughly 2.4 inches) are generally permitted in your luggage. However, any scissors with blades longer than 6cm are strictly prohibited and will be confiscated during the security screening process at stations like London St Pancras or Paris Gare du Nord. Unlike airlines, Eurostar does not have a "checked hold" in the traditional sense for most passengers, so all luggage goes through X-ray machines similar to airport security. If you are carrying craft scissors, kitchen shears, or large tailoring scissors, they will be flagged. In 2026, security staff remain vigilant; if you are unsure, it is best to leave them at home or use a registered luggage courier service. Nail scissors and small vanity kits are almost always fine, but always be prepared to show them to a security officer if prompted during the scan.
