The Bowlz V3 Magnetic Bowl is great for those on the go, whether you're traveling or just out and about. It's perfect for anyone tired of dealing with dirty and hard - to - clean bowls. The bowl comes with a 14.5mm or 18.8mm male joint and has a wider airflow hole. It's made from anodized, food - safe, air - grade 6062 aluminum, which makes it durable and helps it dissipate heat faster than glass. You can choose from multiple colors, and it arrives in a nice custom gift box.
