Superb design and business practices I was delighted with the design and quality of the art and the way in which the transaction transpired. The product came from Europe and I was able to easily track the delivery to my son in Canada. The purchase was made as a metaphor for quiver theory in mathematics which my son is examining for his PhD studies. He was thrilled. What an outstanding design and service delivery

Love my Square Wave I am from England and I have been a big fan of Ivan Black for quite a few years now. His work is simply extraordinary. I finally had a chance to purchase one of his most famous pieces, Square Wave. It came from Italy, it arrived fast, no import duties were due and I have to say that I am impressed with the piece, but also the packaging. It is now part of the decor of my living room and all my friends and guests are instantly drawn to it. It's one of the best conversation pieces I ever had and it's also delightful and relaxing to play with. Definitively recommended and worth every pound. I love to support companies that are creating with love and not mass producing, so that's a plus for me and the fact that I also support a fellow artist makes me proud as well. Well done guys!!!

Absolutely shocking costumer service Absolutely shocking costumer service. Paid nearly £300 for a gift for my partner to then receive a bill from fedEx for £50 shopping fees. I was not aware of this before hand or i wouldn’t of placed the order. Legally you must be noticed of shipping fees upon checkout which I was not. Contacted the company to be told the small print states you may or may not be charged shipping, with no mention of the extreme amount in which it is. Absolutely appalling.
