Has anyone tried the new burb bags for curing?

I purchased some of these burp bags from Amazon because I dint have all the jars and humidity control packs etc.. I spent my wad on seeds, substrate and supplements, there’s very little left for the rest of the process. I’m trying to make due with paper bags lol.
Anyway, here’s a pic of what I’m using. I thought it might control humidity but they dont. I live in the tropics so humidity is always high, and I thought these might be the answer.
I would be interested in hearing anyone else’s experience.

Really, mine are displaying the same humidity in the bag as in the cupboard they are in. I put Boveda and hygrometers in the bags, to monitor the humidity, but they have never registered 58-62% humidity, almost always 70-85%. Am I doing something wrong? Or are my expectations off kilter here?
