These were super great quality and in my opinion a great value.The plastic was nice and thick and the zippers worked great. No defects! I used these for bulk gift bags and they were amazing! I was putting five and a half inch by eight and a half inch notebooks in them and they fit great with room to put my other school supplies items. So they were a great size for my needs. You could use them for tons of different gifting and organization reasons so they are very functional. Again, I want to mention that out of the two packs I ordered there was not a single defective bag! I was highly impressed with the quality! Hope this helps! God bless!
