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

إجابة سريعة
كوب Fressko Glass 300ml هو منتج بسيط وجميل للغاية: زجاج بوروسيليكات، وغلاف من السيليكون، وغطاء لَف. لا يُباع ككوب للتنقل، وهو أفضل لهذا السبب بالذات. إنه كوب الماء، وكوب الشاي، وكوب قهوة بعد الظهيرة الذي يرافقنا دائماً على مكاتبنا.
لماذا أحببناه في النهاية
- إنه صامت. لا يوجد صوت ارتطام بلاستيكي على المكتب الخشبي.
- الغطاء يحميه من الغبار وشعر القطط بين الرشفات، وهي المشكلة الحقيقية على المكتب التي لا يتحدث عنها أحد.
- مظهره أنيق، وهو أمر قد يبدو بسيطاً حتى تمتلك كوباً قابلاً لإعادة الاستخدام ترغب فعلياً في تركه معروضاً أمامك.
غير مخصص لـ
- التنقل داخل حقيبة الظهر (الغطاء القابل للَف مقاوم للطرطشة، وليس مانعاً للتسرب تماماً).
- السوائل المغليّة مباشرة من الغلاية. دعها تهدأ لمدة 30 ثانية أولاً.
التقييم النهائي
9.0/10 لوظيفته الفعلية. اشترِ واحداً، وضعه على مكتبك، واشكرنا لاحقاً.

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.
