Hi there! Our first purchase from Why and Whale was 2 Ocamora 6 piece rainbows and 2 Gluckskafer stackers. This review will focus on the 6 piece Ocamora rainbow with blue as the outermost arch. I had originally been eyeing the green outer arch rainbow, and had planned to gift this one to my nephew. When they arrived, the blue outer arch was just stunning. The colors look pastel online, but they are vibrant in person. Now I am torn about which to gift. They arrived quickly and in perfect condition. Each was packed in its Ocamora box and has shredded paper to protect it in an eco-friendly way. The 6 piece is the perfect size for my son, who will receive it for his 2nd birthday. I look forward to many open-ended uses.
