Review title is Very large capacity for a 311 bag [SEP] So I received this item a few days ago in preparation for upcoming summer trips- two of which I SWEAR I’m going to do carryon only luggage for. I’m a product/makeup girl, so needless to say this will be very hard for me.<br />This bag is huge for a TSA 311 bag- so much so that I asked in the questions section if anyone has had troubles through TSA with it. I decided to see how many items I could fit in it (all sample/travel/trial items). Grand total 44 items, including the 15ml & 30ml bottles from the Doubtless Bay 3pcs airless pump dispenser set and the whole Juvitus cobalt blue 7pc glass bottle started kit (excluding bag).<br />I did- just for kicks- try to fit all these items in a standard quart-sized kitchen zip bag and was only able to get about 80% of what I fit in this bag in.<br />So durability remains to be seen. I will try to update after a couple of my summer trips.<br /><br />Update Jan 2019- the bag is durable nonstretch  plastic, however the zipper is super cheap. So the bag is useless once the zipper goes-which it did. I used it 3 times. The zipper came off the track and separated from the plastic on the bag which from the reviews seems to happen a lot. So you may only get a few uses out of this bag.
