Yes, tweezers are allowed on planes in both carry-on and checked baggage. TSA doesn’t restrict tweezers. They’re classified as a personal care item with no special rules. You can pack them in your grooming kit, toiletry bag, or anywhere else in your bag without any issue.

Since this question usually comes up while packing a grooming kit, here’s the full breakdown of common grooming items and where they can go.

TSA Rules for Tweezers

• Standard tweezers (slant tip, pointed, flat tip): Allowed in carry-on and checked. No restriction.
• Precision tweezers (electronics, eyebrow shaping): Allowed in carry-on and checked. No restriction.
• Tweezers with extremely sharp or very long points: Still generally allowed, but a particularly sharp-tipped pair could theoretically be flagged at the agent’s discretion. In practice, this essentially never happens with standard grooming tweezers.

There’s no size limit, no quantity limit, and no requirement to pack them in your liquids bag or remove them at the security checkpoint.

Full TSA Grooming Kit Reference

Since people packing tweezers are usually packing a full grooming kit, here’s how TSA handles the rest of the common items:

Nail clippers

Allowed in carry-on. Despite the small blade on a nail clipper, TSA explicitly permits them. The attached nail file and the clipper lever are both fine.

Nail files and emery boards

Allowed in carry-on. Metal nail files with a pointed or sharp end may occasionally draw attention, but they generally pass without issue.

Razors

• Disposable razors (Gillette, BIC, etc.): Allowed in carry-on. The plastic housing makes the blade inaccessible.
• Safety razors with the blade removed: Allowed in carry-on. The handle without the blade is fine. The blade itself must go in checked.
• Safety razors with blade installed: The blade can be removed by a security agent. These are technically restricted but usually allowed with the understanding that the head can be separated. Check your airline for their specific policy.
• Straight razors: Not allowed in carry-on. Checked only.
• Electric razors: Allowed in carry-on and checked.
• Eyebrow razors / dermaplaning tools: Generally allowed in carry-on. Similar to disposable razors, the blade is typically guarded.

Scissors

Carry-on: blade must be under 4 inches measured from the pivot point. Most travel nail scissors and small grooming scissors qualify. Any longer scissors go in checked. See our full scissors on a plane guide.

Eyelash curlers

Allowed in carry-on and checked. No restriction.

Curling irons and hair straighteners

Allowed in carry-on and checked. No restriction on the heating tool itself. See our curling iron guide for details.

Hair pins, bobby pins, hair ties

Allowed in carry-on and checked. No restriction.

Thermometers

Digital thermometers: allowed in carry-on and checked. Mercury thermometers: not allowed in carry-on or checked on most airlines due to the mercury spill hazard.

International Rules for Tweezers

No country has a specific restriction on tweezers. They pass through security internationally with no issue. The items more commonly flagged at international checkpoints are scissors (the EU’s 6cm blade limit is stricter than the US 4-inch limit) and sharp-pointed items. Tweezers don’t register as a concern at any major international airport.
