Fressko Glass 300ml review: the desk glass with a lid

快速了解
Fressko Glass 300ml 简约而别致：高硼硅玻璃杯身、硅胶杯套、旋盖设计。它并非作为便携随行杯出售，但正因如此，它的体验反而更好。无论是喝水、泡茶还是享用下午茶咖啡，它都是长期陪伴在我们办公桌上的常客。
为什么我们最终爱上了它
- 安静无声。 放在木质桌面上不会发出塑料碰撞的刺耳声。
- 杯盖能在饮用间隙防尘防猫毛，这才是大家没明说、但办公桌上切实存在的痛点。
- 颜值极高，这听起来似乎微不足道，直到你拥有了一款让你心甘情愿一直摆在桌面上的环保杯。
并不适合
- 放入背包通勤（旋盖仅防溅，并非真正完全防漏）。
- 刚烧开的水直接倒入。先静置 30 秒再倒。
最终评价
就其本职表现而言，可打出 9.0/10 分。买一个放在桌上，你之后会感谢我们的。

Frequently asked
- Is the Fressko 300ml Glass cup completely leakproof?
- No, the Fressko Glass 300ml is not completely leakproof and should not be carried loose in a backpack. During our bench testing, we found that while the twist lid is excellent for splash resistance and keeping out dust, it is not designed to be 100% watertight under transit conditions. Manufacturer specifications class this as a splash-resistant desk cup rather than a travel bottle.
- Can you pour boiling water directly into Fressko Glass?
- You should avoid pouring boiling water straight from the kettle into the Fressko Glass 300ml. Our long-term testing confirms that while the borosilicate glass is durable, it is best to let boiling liquids sit for at least 30 seconds before filling. This simple step prevents thermal shock and ensures the glass remains structurally sound over years of daily desk use.
- What materials is the Fressko 300ml Glass made of?
- The Fressko Glass 300ml is constructed from three simple materials: high-quality borosilicate glass, a protective silicone sleeve, and a hard twist-on lid. According to manufacturer specifications, these materials are chosen for durability and thermal properties. In our bench testing, the silicone sleeve proved highly effective at dampening noise, preventing that annoying clunk when placing the glass on timber desks.
- What is the best reusable cup for a desk?
- The Fressko Glass 300ml is the best reusable cup for desk use, scoring a 9.0/10 in our long-term testing. Unlike clunky travel mugs, its borosilicate glass body and silicone base make it completely silent on wooden surfaces. Additionally, the twist lid is highly effective at keeping out airborne dust and pet hair between sips, making it the ultimate office companion.
- Why does the Fressko Glass cup have a sleeve?
- The silicone sleeve on the Fressko Glass 300ml provides heat protection and noise reduction. During our bench testing, we loved how the silicone prevented the glass from making a loud clunking noise when set down on hard wooden desks. It also offers a secure, non-slip grip, making the borosilicate glass much safer and more comfortable to hold with hot beverages.
- How much liquid does the Fressko Glass hold?
- The Fressko Glass has a capacity of 300ml, making it the ideal size for a standard flat white, tea, or water glass. According to manufacturer specifications, this compact size fits easily under most home espresso machines. Our long-term testing showed this volume is perfect for desk workers who want a steady supply of fresh drinks without taking up too much workspace.
