FAQ

Q1: Will the rhinestones fall off?
A1: They are secured using superglue. They are also secured using a claw-setting technique. Therefore, they are unlikely to fall off during normal use. Avoid contact with hard objects. Also avoid exposure to high temperatures. This ensures they retain their sparkle for a long time.

Q2: How effective is the insulation?
A2: The cup has a double-walled vacuum insulation structure. At a room temperature of 20°C, water heated to 95°C will remain at approximately 50–60°C after 6 hours. After 12 hours, it will remain at 35–40°C. The same applies to keeping contents cold.

Q3: Can I use it for coffee, tea or milk?
A3: Yes. 304 stainless steel is resistant to acids. It is also resistant to alkalis. Therefore, it is suitable for coffee and tea. For perishable drinks such as milk, it is recommended to consume them on the same day. Do not store them for long periods.

Q4: Is it dishwasher-safe?
A4: Not recommended. Hand wash only. Use a soft cloth. Use a neutral detergent. Avoid using steel wool. This may scratch the surface. It may also scratch the rhinestones.

Q5: Can it be used in the microwave?
A5: No. Stainless steel is not suitable for use in the microwave.

Q6: Does the lid seal properly? Will it leak?
A6: The lid features a built-in food-grade silicone seal. When screwed on tightly, it will not leak. This applies even when inverted. It also applies when shaken. We recommend checking that the seal is intact before each use.

Q7: Is it suitable for carbonated drinks?
A7: Not recommended. Carbonated drinks produce gas. This gas increases the pressure inside the cup. This may cause spillage when the lid is opened.
