This minimalist size retains the functionality of stainless steel while fitting into small bags. It's perfect for carrying like an accessory and is recommended for short outings. The double-walled stainless steel construction creates a vacuum-insulated structure, allowing for 24-hour cold retention and 6-hour heat retention, making it ideal for carrying around, such as on outings. Made of durable, rust-resistant stainless steel, it keeps your beverages delicious. 〈Size〉 ・Mouth Diameter: Approximately 3.3cm ・Height (with lid): Approximately 13.5cm ・Capacity: Approximately 200ml ・Weight: Approximately 157g 〈Handling Instructions〉 ・Dishwasher: × ・Dish Dryer: × ・Freezer: × 〈Precautions for Use〉 ・Do not put in liquids hotter than 90℃. Extremely hot liquids can increase internal pressure, causing liquid to spurt out and potentially causing burns when opened. ・When putting in boiling liquids, remove the lid for about 3 minutes to allow the liquid to cool before attaching the lid. ・When carrying, close the lid completely to prevent leaks and use the bottle upright. ・To minimize bacterial growth, do not leave milk-based beverages, baby food, fruit juice, fruit pulp, tea leaves, miso soup, or fermented foods in the bottle for extended periods. ・Never put in dry ice or liquid nitrogen. ・Never use a stove, microwave, or electric oven to heat or preheat this container. ・Be careful when opening the bottle during air travel due to changes in cabin pressure. ・Do not fill with carbonated beverages to the top, as pressure may increase and cause spillage. ・To prevent discoloration, do not expose to direct sunlight for extended periods. ・The pattern on the lid may be slightly off-center from the front (center) of the bottle when closed, but this is a natural occurrence in the manufacturing process and does not affect the quality. Please be aware of this. ・There may be slight gaps or individual differences between the lid and the body of this product, which are unavoidable in the manufacturing process. There are individual differences in the position and angle of the gaps, and they may appear slanted, but these are due to the characteristics of industrial products and do not affect the original functions of the product, such as water leakage or heat retention performance. Please understand this beforehand.
