Ti Toki bottles - Orzel and Crown Lynn are different sizes

Here are my Ti Toki bottles side by side - Orzel is 750 ml and Crown Lynn is 500 ml.  Orzel is 30 cm tall and Crown Lynn is 25.

Here are the two tickets still on both bottles. Crown Lynn (500 ml) on the left and Orzel on the right.

And here is the base of my newly acquired Orzel bottle.
