I bought these to use at the airport when I went away last September & they did the job perfectly. They fit in more than you'd think. I'm now going to purchase again for my upcoming holiday. Can't complain at the price either, my friends bag split before we got to the airport & she had to pay £2 from the airport vending machine for a low quality one.
These cost me £1.88 from Layton's bits and bobs, and I'm very happy with these bags.
I wanted some plastic resealable bags as a temporary solution for sealing some stuff up with silica gel to keep it dry, and also to put my travel toilettries in when I next fly somewhere. These bags seem ideal for these purposes - the plastic doesn't feel too thin, and the 'zip' mechanism works well. They are just under 15.5cm x 20cm by my measurements, so should be fine for carrying liquids on planes. The bottom of the bag has got a little pleat in it so it has about 5cm of depth, which makes it much easier to fit stuff into it.
I'd happily recommend these to a friend - a good price if you only need a few resealable bags, and they've served me well so far.
Best ones I have purchased strong plastic good zip-loc. Better than a lot of these bags around including the free ones at the airport, but I bubble wrap a lot of liquid and sun lotion stuff before I place in the bags anyway if they need to go in my case. Will purchase again,saves scouting around shops for them as they are not always that easy to find for some silly reason.
These are really good bags, well made and no-nonsense zips - they worked every time. The size was good too as they held enough so that you could see the contents from both sides, nothing was hidden in the middle, well not if you don't over fill them. I shall certainly be buying more as they have many uses.
