This is the same Large Circular Tray of 60cm diametre as before but with blue internal sides which is easier to produce and thus reflected in the price difference. 
I was asked to make these Circular trays big enough for group work and small enough to be acomodated in a standard therapy room. Like the Octagonal or the Small 50cm diametre trays this one is stunning for Jungian work - some people are using them for personal self care in their practice.
Highly recommend a lid with this tray as it allows multifunction as table top and protection between sessions.
