I've had the large Bagley Grantham vase (8") and the delightful, little 4" tiny version, but I have not seen the mid size before. It's 6" at its tallest point (15cm). How unusual is this mid size? Or have I simply led a sheltered life and they are everywhere

The photo shows the 6" on the left and the 4" on the right. The angle of the shot makes the size difference look greater than it actually is.
