Stop buying overpriced travel minis. The Crossing Silicone Leak Proof TSA Approved Travel Size Bottles (90ml, 4 Pack) lets you bring your own shampoo, conditioner, body wash, and lotion in four durable, refillable silicone bottles — each sized to meet TSA carry-on requirements and built never to leak. An innovative 3-layer lid design with firm seals locks liquids in tightly, even when your bag is tossed on a luggage belt. At 90ml each, these are the largest TSA-approved carry-on bottles available — maximising how much product you can take without checking in your toiletries bag. Refillable, reusable, and available in a fun assorted colourway.

Which size is right for you?
Both versions share the same leak-proof design and BPA-free silicone — the difference is size and use case:
Why it works
Innovative 3-layer lid — zero leak guarantee
The 3-layer lid design creates multiple sealing points that prevent liquids escaping under pressure, temperature changes, or impact. Unlike basic flip-cap bottles that leak in checked or carry-on bags, these stay tightly sealed throughout your entire journey.
TSA approved at maximum 90ml capacity
At 90ml per bottle, these are filled to the maximum volume permitted under TSA and international carry-on liquid rules (100ml limit per container). You get the most product possible without a single bottle needing to go in your checked bag.
BPA-free silicone — safe for all toiletries
Made from BPA-free food-grade silicone that won't react with shampoos, conditioners, body washes, or skincare products. No chemical leaching, no altered formulas — what goes in comes out exactly as it should.
Wide opening — easy to fill and clean
The wide-mouth opening makes it easy to pour or squeeze product in from full-size bottles at home, and equally easy to clean thoroughly between refills. No funnel needed for most products.
Refillable and reusable — saves money every trip
Use your preferred shampoo, conditioner, or body wash — not whatever the hotel provides or whatever travel mini happens to be on shelf. Refill at home before each trip and reuse indefinitely, cutting both cost and single-use plastic waste.
Assorted colours — easy to tell apart
Each bottle in the 4-pack comes in a different colour, making it effortless to tell your shampoo from your conditioner from your body wash at a glance — no squinting at labels in the shower.
Lightweight at just 40g per bottle
All four bottles together weigh just 160g empty — less than a standard travel-size product. They add minimal weight to your carry-on while giving you four times the product flexibility.
What can you fill them with?
These 90ml bottles handle virtually any liquid or semi-liquid toiletry:
Shampoo
Conditioner
Body wash
Face wash
Lotion
Sunscreen
Shaving gel
Mouthwash
Hand sanitiser
Toner

Care instructions
Rinse thoroughly with warm water between product changes to prevent residue build-up inside the bottle.
Can be hand washed with mild soap or placed on the top rack of a dishwasher.
Allow bottles to dry completely with lids off before refilling to avoid diluting your products.
Store with lids tightly closed to maintain the 3-layer seal between trips.
Do not fill beyond the 90ml mark to ensure the lid seals correctly and remains TSA compliant.
Why Crossing
Maximum legal carry-on volume
At 90ml, these bottles hold the most product legally allowed in carry-on baggage — so you always have enough shampoo and body wash for your trip without checking in a bag.
Four bottles, four products
One pack covers your full toiletry routine — shampoo, conditioner, body wash, and face wash — all in assorted colours so you never mix them up in the shower.
Built to last, not to be thrown away
BPA-free silicone is more durable than plastic and won't crack or discolour over time. These bottles are designed to travel with you for years, not just one trip.
