Polish Post Seal.

[CtahhR]

I was amazed recently when on receiving a large package from Poland to find that the twine holding the package safely together came with a metal Polish Post seal holding the twine together.
A truly fantastic tradition to retain into the 21st century.

I must admit I have never seen this, so probably it is not used too often.

Al-muell,

It may be that these are used for international mailngs only.
