Danish design is superlative - they have an incredible talent for deconstruction and then making a product simple yet spectacular at the same time.
'Inception' is one vase in a darker tone, sitting inside another in more transparent base so this can be used as one vase or separated and used as two! - please see images! We have blue( one vase is dark blue and the other a pale blue) and the other is a smokey grey teamed with a very pale yellow. There - I hope that I have explained the concept succinctly?
