This is a double-wall glass with a gold filter from Cores. I received it from an acquaintance, but I am selling it because I don't use it. Brand: cores Capacity: 300 milliliters Color: Normal Product Dimensions: 9 depth x 12.5 width x 10.5 height cm Features: Heat retention Coffee Maker Type: Coffee Infuser Features: Heat retention Coffee Maker Type: Coffee Infuser Cores is a coffee tool brand that conveys the diverse individuality of specialty coffee to each coffee lover. Since it does not require extraction equipment such as a press or dripper, you can easily enjoy "freshly brewed" coffee even by yourself. In addition to the double wall that keeps hot drinks from cooling down easily, it has a lid so you can also steam the coffee properly. The mesh is coated with pure gold, making it resistant to chemical changes and the filter that has the least impact on taste and aroma. Contents: 1 piece (W12.5 x D9.0 x H10.5cm) Thank you.
