Three possibly Pirelli or Murano glass figures.
Penguin, blue fish and purple/white fish.
The penguin has a broken foot but still stands up, and the purple fish looks like it may have been attached to something at some point as it has an extra piece of glass underneath that looks broken. The purple one also has a crack on the top. Blue one is in good condition (see photos).
These are all small, under 6cm in size.
