Carry a compact serving of water or another compatible beverage with this approximately 300 ML Stainless Steel Water Bottle. The small reusable format can be convenient for school, office, travel, picnic or other short outings where a lightweight bottle is preferred. Wash thoroughly before first use and clean after every use. The stated capacity is approximately 300 ml. Exact stainless steel grade, single-wall or double-wall construction, insulation, lid mechanism, drinking spout, colors and surface finish vary by model. Do not claim vacuum insulation, specific temperature retention or a particular stainless steel grade unless verified. Metal bottles should not be placed in a microwave. If used for warm beverages, check the temperature before drinking because exterior surfaces may become hot depending on the construction. Secure the lid before carrying but keep the bottle upright unless leakproof performance is confirmed. Avoid prolonged storage of beverages not recommended by the manufacturer. Clean and dry thoroughly before storage and inspect the lid seal periodically for wear or damage.
