Hi A.,
I would double check with Pottery Barn at the actual store--I bought them there. Mine are square and white. Also, my friend just bought some at Babies r Us--also white. They sell them all separately there, whereas, I bought a pack of 3 at Pottery Barn. I got mine at the Maple Grove Pottery Barn, and my friend got hers at the Roseville Babies r Us. Take care!
