Review on 🔋 Highly Effective 6PACKS Rechargeable Desiccant Packets with Indicator by Andres Imaging

I usually seal one of these with every spool of 3D printer PLA filament for long term storage, but you can never be sure it will help. The filaments always print well after storage, but it is almost impossible to prove a negative result. That is, until the consequences of not using a desiccant can be ignored. Here's a picture of plumeria flowers that I need for a kids art/science project. All samples were collected from the same plant (stem), cooked at the same time and pressed into Foodsaver bags and stored together under the same conditions. However, one set included a Wisedry desiccant (package is shown in photo). Those that weren't will turn black after 1 day, lose color and seep into the paper insert! The ones filled with desiccant still look bright. You can judge if they really work. I like how you can tell when the desiccant properties are depleted.
