Quality tiles from large tile chain

[Italy]

You are right both.
the arrow, is the mold.
And if tiles have orthogonal problems.
Following the arrow, you have the same size, always on the same side.
But this does not solve the problem.
If one side is 1mm wider,
after 5 files, you have 5mm longer in comparison to another.
I never looked at the arrows, though I knew,
What that said to Paul.
In any case, those tiles are just s.it.

My assumption was that if there were not specific instructions on the box of which way to fit them then the arrow was just the way they were to be laid in the kiln.
