For U.S. air travel, toothpaste is allowed in a carry-on only when the container is 3.4 oz or 100 ml or smaller. One+ is a full-size 4.23 oz tube, so it belongs in checked baggage unless you use a separate compliant travel option.
For road trips, trains, or checked luggage, the 120 g tube offers about 90 brushings. Pack the brush so it can dry, keep the routine accessible, and verify local airport rules when traveling outside the United States.
Checked bag: yes. Standard U.S. carry-on: too large.
The standard One+ tube is labeled 4.23 oz, which is larger than the TSA carry-on limit of 3.4 oz or 100 ml for pastes. Put the full-size tube in checked baggage or choose a compliant travel-size container or product. The final checkpoint decision rests with TSA.
No. Brush twice daily, clean between teeth, and keep the brush able to air-dry. Travel mainly adds packing, water, meal timing, and routine disruption. A compact kit helps only if it is accessible when you actually need it.
Klyyr estimates about 90 brushings from a 120 g tube. That can cover an extended trip for one person, but the full-size package is not carry-on compliant under the standard U.S. 3-1-1 rule. Trip length and baggage type should decide what you pack.

A full-size 120 g tube with roughly 90 brushings. It exceeds the standard U.S. carry-on paste limit.
Yes, under the TSA liquids rule when the container is 3.4 oz or 100 ml or smaller and fits in the quart-size liquids bag. Toothpaste is also permitted in checked baggage. Rules can differ outside the United States.
The standard tube is labeled 4.23 oz, so it exceeds the TSA's standard 3.4 oz carry-on limit for pastes. Klyyr should not market this full-size tube as carry-on compliant.
A travel container must be compatible, clean, sealable, and within the applicable size rule. Because repackaging can affect hygiene and labeling, a purpose-made travel toothpaste is often simpler. Check airline and destination rules before departure.
Rinse it, let it dry, and avoid sealing a wet brush in an unventilated case for long periods. Keep it separate from dirty surfaces and replace it when bristles fray or after the interval recommended by your dentist.
