blue plastic tumbler

Many blue tumblers are made from generic plastics; some listings specify polypropylene (PP) or high‑density polyethylene (HDPE) for parts such as lids. Several items are also labeled BPA‑free. Check product details to confirm the specific plastic and any safety claims.

Capacities range from about 10 ounces up to 20 ounces, with common sizes including 10 oz, 13.5 oz, 16 oz, and 20 oz.

In the sample set, overall heights span roughly 4.75 inches to 9.5 inches, and widths range about 3.2 inches to 4.5 inches, depending on the style and capacity.

Several listings call out grip features such as ergonomic handles, textured finishes, or a textured sleeve to provide a non‑slip grip and improve handling.

Listings include toddler and preschool options (examples show suggested ages like 12 months+ and 3 years+), and other tumblers are described for everyday adult use at home, at work, or on the go.
