Really smooth nail care.
The hard glass body of this nail file
is acid treated to make the finest of
pores; this results in an especially
smooth surface that doesn’t damage
the nails when filing. Instead of tearing
at the nails, it gently straightens and
smoothes the edges, which prevents
the intrusion of dirt particles and bacteria.
Hardened glass will not wear out
mechanically, so that this file will never
turn dull. There is no mineral abrasion.
Its only weakness is that, just like any other glass object, it can break, in spite
of the very durable material.
Our file comes from a Czech manufacturer,
who invented the hardened glass
file in the first place. There are many
crude imitations on the market.
