C22U5LA GE2B

A variation of this product (widely been used has) for millennia -since 400 B.C.E., in fact.

A number of my friends said they thought that it (had invented originally been) by the Egyptians.

However, the first "recipe" for the product as we know it today (been had created apparently) by the Chinese.

Historians say it (used had been obviously) to protect bronze mirrors in the second century.

In addition, records show that medicines (had wrapped been carefully) in it for safekeeping.

A replacement product (yet been discovered not has), unless you consider computer technology.

The idea we can live without it (not has materialized completely still), but will it ever be obsolete?
