They are a good size and they get the job done. I would definitely purchase again.I am very happy that I made this purchase. I bought these containers to hold my homemade cold pressed juices and I they are holding up beautifully. I highly recommend the purchase of these containers.These are not a full 12 ounces and they leak. I will be returning them.They're exactly as expected but when I opened the package I had 12 containers and 10 lids. I didn't need them right away so by the time I opened them it was too late to return.When it was hard to find cleaning products when Covid first came out I found the strongest version of Lysol that could be diluted to make other bottles. I used these bottles to make 12 more bottles of the Lysol solution and shared it with family. They were easy to travel with because there was no spillage - I also used some of the bottles for an alcohol based solution and the clear of the bottles helped to identify which was which. Because they are tall and slim they are also easy to store. All around a great product.There should be a warning that these are not recommended for dishwashing. I washed two at normal temperature and placed them on the top rack; they are now ruined. Thank goodness I didn't wash the whole pack at once!Ordered a 12 pack of bottles. Came with 12 bottles and only 11 lids so part of the product was unusable for the intended purpose of what it was bought for.I’ve ordered several times but the last couple of orders have come to me opened and or crushed. It was disappointing to say the least.I brought these to use to make sensory bottles for my little boy. They are amazing for that, seal well (even though I taped them also) great size and shape and really pleased with themGreat quality and well worth the money! Used mine to freeze smoothies in, I just take one out of the freezer each night and leave it to thaw in the fridge for the next morningIn 2013 I was snowed in for three weeks & froze a 2 litre container of milk which used up a lot of space & took ages to defrost. These bottles mean that I can freeze almost 2 litres of milk in six bottles.I have left them standing up but they do not take up much freezer space & thaw quickly in the fridge.I bought these to personalise for friends and family. First lot were exceptionally good quality, came in a box and not a single thing wrong with any of them except a small scratch on one of them which was easily hidden. I decided to buy another lot, my mistake! Came in a bag this time and out of 12 bottles, 4 are usable! Bashed, bent out of shape and broken lids. Not too happy.ETA: I was given a refund for the bottles but I'm very wary about ordering more. Puts me off buying again as don't want the same thing to happen.Great product for cutting down on bottled water reliance or for homemade iced coffee. Dirt cheap and great quality. Don’t do well in the dishwasher - hand wash with warm soapy water, rinse well.
