A 1,000mL storage bottle made of heat-resistant glass with a silicone rubber packing. [New and unused] Weighs 400g. It's incredibly light! On HARIO's website, this shape is listed as 2000ml, but this is an older model, and this shape is 1000ml. - Brand: HARIO - Model Name: GHB-1000 - Practical Capacity: 1,000mL - Material: Heat-resistant glass - Heat Resistance Temperature: 180℃ I am also selling a 2000ml model with slightly squared shoulders. Please take a look if you'd like. If you purchase both together, I can offer a slight discount, so please leave a comment. Bulk purchases are also welcome.
