tumbler bowl

Tumbler bowls are made from glass, silicone, HDPE (high‑density polyethylene), polypropylene, and post‑consumer recycled plastics. Several listings explicitly call out glass, silicone, HDPE, and recycled plastic in their product descriptions.

Durability varies by material: some are described as heavy‑duty or chip‑resistant glass, while others are break‑resistant recycled plastics. Product copy and reviews for several items explicitly highlight durability or break resistance.

Yes. Several listings describe the bowls as stackable or ultra‑stackable for space‑saving storage, with certain plastic models specifically noted for easy nesting.

Capacities range from small single‑serve bowls up to large serving bowls — roughly 8 fl oz up to 114 fl oz. Common sizes listed include about 8 fl oz, 10 oz, 12 fl oz, 30 oz, 40.5 fl oz, 84 oz and 114 fl oz.

Tumbler bowls appear in round, square, and some irregular decorative shapes — for example, one glass bowl is described with a scalloped edge as an irregular decorative form.

Some plastic bowls list post‑consumer recycled content — multiple listings show 20% post‑consumer recycled plastic, one listing shows 70% post‑consumer recycled plastic, and certain bowls are made from recycled HDPE (milk jugs).

Features include a smart lip for scraping and scooping, a collapsible base for steaming and serving, scalloped or widened edges for easier handling, and wide, curved bowl shapes that make serving easier.
