Common capacities range from about 10 ounces up to 40 ounces. Typical sizes listed include 10 oz, 12 fl oz, 13.5 oz, 14 oz and 40 oz — check each product listing for the exact available sizes.

Most are made from plastic (commonly polypropylene) or stainless steel. Several listings specify 18/8 stainless steel, and some products combine polypropylene and stainless steel.

Age guidance varies by product: some listings specify toddler/kid ranges (for example, 3 years and up), one referenced a 0–1 year suggestion, and many do not specify an age. Always check the product’s stated age recommendation and safety information before buying for young children.

Avoid abrasive cleaners and scrubbers; spot‑clean or wipe with a soft, non‑abrasive cloth. Be gentle with straw valves and silicone membranes when cleaning to prevent tearing or damage.

Common features include leakproof or spillproof lids, valve or no‑splash straw systems, splash‑resistant lid designs, and in some cases leakproof silicone seals or reusable spill‑resistant straws.

Many listings advertise cupholder compatibility, using terms like cupholder‑friendly or cupholder‑compatible silhouettes and noting fit with car cup holders and some booster seats.

Listings reference post‑consumer recycled content and recyclable plastics. Examples include recycled HDPE (milk jugs), products labeled as containing recycled material, and some claims of high percentages of recycled 18/8 stainless steel (e.g., 90%). Several items also note BPA‑free construction. Review each product page for full sustainability details.
