I put them in a bag of 69% Boveda and both were rejected by 3-4%. Not a bad product, just mentally realized how outdated they are. Not a bad product for the price though. Also, there doesn't seem to be an option to customize them. To update. You are completely useless. I can't get them to provide the right humidity, which is very important for my cigars. Buy a humidor. Here's what I ended up doing.
