very large capacity for a 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 methis bag is huge for a tsa 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 items including the bottles from the doubtless bay airless pump dispenser set and the whole juvitus cobalt blue glass bottle started kit excluding bag 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 of what i fit in this bag inso durability remains to be seen i will try to update after a couple of my summer tripsupdate jan 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 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
