Q: Is your glassware dishwasher and microwave safe?
A: Most of our products are made from [borosilicate/soda-lime] glass. While they are generally dishwasher safe, we recommend hand-washing to maintain the glass’s clarity over time. Please check the specific product description for microwave compatibility, as some items with metallic rims or vacuum seals are not suitable for microwave use.

Q: How do I prevent thermal shock?
A: To avoid cracking, avoid sudden, extreme temperature changes. Do not pour boiling water into a cold glass or submerge a hot glass in ice water immediately after use.

Q: What should I do if my glass arrives broken?
A: Please inspect your order upon receipt. If an item is damaged, email a photo of the product and packaging to support@nnglass.us within 48 hours. We will arrange a replacement at no extra cost.

Q:How can I contact customer service?
A:If you have any questions regarding your order, products, or services, please contact our Customer Service Department.
