These are absurdly expensive for what they are, but they do work very well. Currently using them in the Bambu Lab AMS and they fit great in the bambu filament rolls. They fit fine in prusament rolls, but are off angle because the inside of the roll is larger than the spool opening. Haven’t tried recharging them yet but i’m sure they’ll do fine. I did have an issue with the top popping off if I dropped it on the table/floor. Easily fixed by taping the lid to the can.

Small containers that do a great job pulling moisture from the air to keep your filament dry.

They are a lot smaller than I anticipated but they do fit into the center of the spool. I'm second guessing how much moisture these actually absorb because there's not a lot of dessicant in them.
