I thought the plastic was going to be thicker, but it is thick and resistant enough. The seals are great on the sides and they are very easy and convenient to use. I am using them for sending green coffee samples and they perfectly holds 325 grams and perfectly full with 350 grams. The size is ideal because the bags look full, and we reduce plastic waste. Plus, they are reusable, perfectly sterile and no smells!

Our lab uses these every day to keep petri dishes from flooding when submerged in a water bath during fecal coliform analysis. These are the real Nasco brand and Nasco quality at a price that couldn't be beat by any lab supply house. We've ordered twice so far and will be ordering again as needed.
