Customer Testimonials & Reviews

- LMS (★★★★★: Reviewed in the United States on January 28, 2026)

"I absolutely love the Nutcracker mugs and drink ware this company produces! They are both cheerful and useful! I thought I would mind that this item isn’t supposed to go in the dishwasher, because, as a teacher, I am constantly trying to get rid of germs. But, I am fine with handwashing this metal mug! I keep it in my bathroom as both a seasonal decoration and a mug I use daily! It is adorable! This is the third Nutcracker mug I have purchased from this company and they are all beautiful and of very high quality! The size is perfect! The plastic lid is leak proof! It keeps drinks both hot and cold, and it is the perfect thickness and weight! I highly recommend this company!"
