Leak Proof Sleeves for Travel Container, Toiletry Covers for Leak Proofing in Luggage, Silicone Travel Bottles Leak Proof Tool Fits Most Size

They work great for a while but start to rip after maybe a month or so of use.

Easy to stretch over bottles. Figure on 10% of the tearing once on the bottle. These were put on once and not touched for 4 months. No experience with putting the on and taking them off and reusing them.

They stretch nice over bottles and lids, but I did poke my finger through 2 of them. None of our stuff leaked during our flight so they did work nice. Gave some to my mom for her camping trips to keep ants out of her stuff.

These stretch and stay on my travel bottles very well. Now I need a trip to test them! I will hopefully update this once I travel on an airplane to let you know if they work. I have some travel shampoo bottles that tend to leak so it’ll be a great test. Pros: Sturdy, stretchy, clings Cons: while I bought 4 sizes there are perhaps minor differences in the sizes (the different colors). Honestly they seemed similar. Update: Worked out great on my trip. These were used on a few bottles that previously leaked and NO Leaks! I would highly recommend.

I haven't used it yet, but my sister told me that it's excellent for traveling and preventing things from spilling and it’s ease for use.
