MoMA design store a couple days ago. The set goes from $220. MoMA lists them as knitted baskets, but up close it is clear they are crocheted.
They are made out of neoprene, a flexible rubber used in the automotive and plumbing industries. Interesting material, soft to the touch and holds the bowl shape well.
The designer is Rosanna Contadini. She and two other designers, Isabella Nardone and Analia Restrepo, design handbags, home decor products, and jewelry all produced from neoprene. Check out there other items at Neo
