304 Stainless Steel Insulated Protein Shaker Cup with Tea Insufer

Frequently Asked Questions

Q: What is the capacity of the shaker cup?

A: The shaker cup has a capacity of 350ml (approximately 12 ounces). This compact size is perfect for mixing protein shakes or staying hydrated during workouts, and it fits easily in most backpack side pockets or cup holders.

Q: How does the vacuum insulation work, and how long does it keep drinks cold?

A: The double-wall vacuum insulation creates an airless layer between the inner and outer walls, minimizing heat transfer. Cold drinks typically stay cold for up to 12 hours, and hot drinks remain warm for up to 6 hours. The stainless steel construction also prevents condensation on the outside, so your hands and bag stay dry.

Q: Is the lid truly leak-proof for shaking protein powder?

A: Yes, the lid is designed with a tight-sealing silicone gasket that prevents leaks when closed securely. For best results, ensure the lid is fully tightened before shaking. The wide mouth also allows easy addition of powder and liquids, plus thorough cleaning after use.

Q: Can I use this cup for hot beverages like coffee or tea?

A: Absolutely. The 304 stainless steel and vacuum insulation are safe for hot liquids. However, note that the exterior may become slightly warm over time, though much less than a non-insulated cup. Use caution when handling hot contents, and avoid overfilling to prevent spills when opening.

Q: Is the cup dishwasher safe?

A: For longevity, we recommend hand washing the cup and lid with mild soap and warm water. While the stainless steel body is durable, dishwasher cycles may degrade the powder coating finish or affect the seal over time. Hand washing helps preserve the vacuum insulation and appearance.

Q: Can I customize the cup with my logo or choose a specific color?

A: Yes, the manufacturer offers customization options for bulk orders. You can select from gradient powder coating colors and have your logo printed on the cup. Minimum order quantities may apply. Please contact the seller for details on pricing and customization requirements.

Q: Does the cup have a handle for easy carrying?

A: Yes, this shaker cup features a sturdy handle attached to the body, making it easy to carry during walks, gym sessions, or commutes. The handle is integrated into the design and does not interfere with stacking or storage.

Q: Is this cup BPA-free and safe for daily use?

A: Yes, the cup is made from 304 food-grade stainless steel and is completely BPA-free. All materials used, including the lid and seal, are non-toxic and safe for repeated use with water, protein shakes, or other beverages.

Usage Instructions & Precautions

• Hand wash with mild soap and warm water. Avoid using abrasive cleaners or scouring pads.
• Do not microwave or freeze the cup.
• For hot liquids, allow the beverage to cool slightly before closing the lid to prevent pressure buildup.
• Ensure the lid is securely tightened before shaking to avoid leaks.
• Not recommended for carbonated beverages as pressure may build and cause leakage.
• After washing, store with the lid off to allow the interior to dry completely.
• Avoid dropping or exposing the cup to extreme impacts that may damage the vacuum seal.
• Dishwasher use is not recommended as it may degrade the powder coating and affect insulation performance over time.
