Tupkee 14 oz Double-Wall Glass Travel Cup with Hand-Blown Borosilicate, Lid & Silicone Sleeve (Jacaranda)

If you like your drinks to taste clean and you also want your cup to hold up to real daily use, this Tupkee double-wall glass travel cup is built around that idea. It’s made from borosilicate glass and designed to stay comfortable to hold while keeping your tea or coffee hot—or colder—for longer.

Key takeaways on what you’re buying

This is a reusable travel cup that combines hand-blown borosilicate glass, a leak-resistant lid with a silicone seal, and a silicone sleeve for grip. On paper, the main appeal is pretty straightforward: less worry about odd tastes (no mention of plastic/metal contact) and better temperature handling thanks to the double-wall structure.

It’s also one of those products where small details matter. The silicone sleeve and anti-slip base are there so the cup feels steadier in hand, and the lid includes an opening so you can use a straw while you’re on the go (as long as your straw works with the opening).

What stands out in everyday use

The double-wall glass construction is the headline feature here. You get insulation for hot drinks and helps reduce how quickly the drink warms up or cools down. The outer glass wall is also intended to feel more comfortable to the touch, which is a big deal with glass travel cups—nobody wants an “oven mitt” moment after a fresh pour.

The lid setup is meant to be leak-resistant thanks to a silicone seal. That’s the practical difference between “cute cup on your desk” and “actually safe to toss into a bag.” The brand also emphasizes that the silicone is food-grade and BPA-free, and that the lid system is designed to avoid unwanted flavors.

For a quick, realistic micro-experience: imagine making iced coffee, placing the lid on securely, and sealing it before heading out. The goal is that the drink stays cold longer and you don’t get the same condensation-and-slippery-hand situation you often see with less insulated cups.

Materials and build quality (and what to keep in mind)

This cup uses hand-blown borosilicate glass, described as heat-resistant and capable of handling thermal shock and temperature changes (and it’s also described as suitable for microwave and freezer use). That’s a meaningful set of claims, but it still comes with a simple reality check: glass can be durable, yet it can still break if dropped or mishandled.

One important limitation to note is cleaning. The design includes removable silicone components for deep cleaning, but the instructions provided emphasize hand-washing only. If you rely on the dishwasher for everything, this may feel like a step backward.

Who it suits (and who should think twice)

It’s a good match if you want a reusable travel cup that prioritizes insulation, comfortable handling, and a lid system intended to resist leaks. It’s also a solid pick if you care about cup taste—especially if you’ve disliked that “plastic cup” flavor or residue feel from other travel designs.

It may not suit you as well if you’re looking for a set-it-and-forget-it dishwasher option. It also might not be the best fit if you frequently need to toss your cup around without any concern for glass durability.

Is it worth it?

Buy it if you want a glass travel cup that focuses on insulation, comfortable grip, and a silicone-sealed lid designed to help prevent leaks—while keeping the drink experience “clean” (no mention of plastic/metal taste). The double-wall design is the reason this can feel more premium for everyday hot or iced coffee/tea routines.

Skip it if you want dishwasher convenience, or if you don’t want to manage hand-washing. Also, if your routine involves a lot of rough handling, you may want to think about whether glass is the right direction for you.
