Elysian Blue Color Indicating Desiccant Silica Gel Beads, Industry Standard 2-5mm Rechargeable Moisture Absorbent (Blue to Pink) Pack of 100 Gram

The item is from fresh stock, i.e., June 2020 and expiry date is June 2021. Actually Silica Gel has no expiry date as it can be reheated and used again and again. I am using 500 gms standard quality Silica Gel for last 12 years in my camera box without any problem. Silica Gel is the most effective and cheapest method of protecting expensive equipments, especially optical equipments like camera, microscope etc. This is because moisture in air allows fungus to grow on lens surfaces and this degrades the lens quality. Packing was good. Hence all globules were dark color.

From left to right:1. Original with no moisture2. With partial moisture absorption3. Fully absorbed (the bead here got broken into pieces as the bead was dropped in puddle of water this is not a real life scenario as the product is designed to absorb moisture from air not to absorb the whole puddle of water)

I am using this to fight fungus on my camera and binocular lenses. Works like a charm. Colour indication works well.The only thing you should be CAREFUL about is that, after handling the product, wash your hands thoroughly. The coloring compound can be toxic.

I love it! It's so pretty and very effective for drying flowers. I easily reactivated it in the microwave

The product delivered on time.The quality of product is good. Absorbs moisture quickly and tuns pink in color. That's all chemistry behind it.I am satisfied with the quality and product received as mentioned.As once it turns pink, it is almost saturated with moisture and its capacity to absorb moisture reduces.Will discuss soon about its recyclability.
