Self Indicating Silica Gel

Self-Indicating Yellow Silica Gels 

The silica gel is contained in a clear plastic bag.  It has many microscopic holes to let the moisture slowly through. 

The silica gel then will indicate that moisture is present.  The yellow beads will change to a green colour

PLEASE NOTE . These are silica gel and not desiccant clay. Silica gel is a desiccant – it adsorbs and holds water vapour

In electronics, scientific and optical instruments it prevents condensation, which might damage the electronics. Each sachet will absorb up to one third of its own weight in water vapour

The gels come packed in air tight bags for a long shelf life

Printed on each sachet :- DESSICANT GEL Do not eat
