Material: Heat-resistant glass Capacity: 550ml Size: Mouth diameter 10cm x Height 21.5cm Remarks: Dishwasher and dryer safe Suggestions for use: Eggs, coffee, milk, cream, Mother's Day gifts, new life, etc. Notes: * If there are colors, the actual color may differ depending on the monitor's display. * Tips for using glass products for a long time: During the manufacturing process of glass tableware, slight distortions, fine scratches on the surface, small air bubbles, wrinkles on the bottom and sides, water droplet stains during cooling, and a cloudy phenomenon may occur. These do not diminish the product's characteristics during use, so please use them with confidence. Returns and exchanges are not accepted for these conditions. * When taking out after heating in a microwave, avoid cold surfaces and place it on a material that buffers heat, such as cloth or wood. * Dishwashers are not recommended because the water pressure and temperature vary depending on the manufacturer. * Sizes are measured flat, and although we strive for consistency among staff, there may be slight variations. * Glass breaks due to tensile stress. To use glass products, including heat-resistant glass, for a long time, it is very important to avoid scratches as much as possible, such as by not hitting them with metal or hard objects like ceramics, or scrubbing them with abrasive sponges. * Most substances, including glass, expand when heated and contract when cooled. Thermal breakage usually occurs due to rapid cooling or rapid heating. Heat-resistant glass has very small expansion and contraction due to heat, which helps to suppress the generation of stress caused by this expansion and contraction, making it more resistant to heat. * When glass breaks, it always breaks from a scratch on the tensile stress side. The stronger (deeper) the scratch, the easier it is to break with less stress. Scratches grow (become deeper) with repeated use, and the strength of the glass decreases.
