To the naked eye, it's nearly impossible to see the details: The glass penguin, only measuring half a centimetre, spreads its wings and is painted in four different colours.

According to Guinness World Records, this tiny figurine is part of the world's "largest collection of penguin-related items", which belongs to German couple Birgit Berends and Stefan Kirchhoff.
