These knife rust prevention tabs make your sealed knife storage box into a Rust Free Zone™. Just one tab protects a volume of approximately 0.9 ft³ or a more than 6 gallon/22 litre container.  Store your knives within about a half a foot of any Plastab and seal the storage container for epic rust prevention for up to 2 years!

Plastabs are thin, light, rigid polyethylene squares made with corrosion-inhibiting technology moulded right into the plastic. The patented formula emits a harmless vapor of rust prevention molecules that form a protective layer around nearby metal surfaces. Their small, slender shape makes Plastabs perfect for protecting critical surfaces within the narrow slot of a knife case.

These specially designed plastic tabs provide hassle-free, long-lasting rust protection for up to two (2) years.

Zerust products are non-toxic, odourless and will not leave residue on electrical or contact surfaces. Stop rust before it starts!
