BJPKPK Coffee Tumbler 18 oz

The double-wall vacuum insulation is the main draw here: it’s designed to keep drinks hot or cold for hours, while the tapered shape is made to fit most car cup holders. This 18 oz stainless steel tumbler gives you two ways to sip: drink through the flip opening or use a straw. That flexibility suits a commute, desk, or day out when you want a reusable cup close at hand. One detail matters for everyday carrying, though: the straw connection can leak if the tumbler is inverted, so treat it as an upright cup rather than a bag-ready bottle.

Technical details

BJPKPK lists this tumbler as double-wall vacuum insulated and made from 18/8 food-grade stainless steel. Its threaded lid has a flip opening for drinking directly and a center opening for a straw. The product name also identifies it as BPA-free and dishwasher-safe, and the package description includes two reusable straight straws. No insulation duration beyond “for hours” is specified, so there’s no stated time guarantee for keeping a drink at a particular temperature.

The lid’s two drinking options are useful if your routine changes: sip from the flip opening at your desk, then use a straw while driving. It makes sense if you want a cupholder-friendly tumbler with a straw option and don’t need to lay it on its side. Compared with a bottle designed around secure, sealed transport, this format prioritizes easy sipping over confidence when tossed into a bag.

Compatibility & requirements

The tapered profile is intended to fit most car cup holders, not every holder, so the fit may depend on your vehicle. The listing doesn’t provide tumbler dimensions. If your cup holder is unusually narrow or shallow, the product details here aren’t enough to confirm a match.

The lid accepts a straw through its center opening, and two straight reusable straws are included. The manufacturer’s own usage note warns that liquid may escape through the silicone grommet and vent around the straw if the filled tumbler is turned upside down. That makes upright placement the safer choice, particularly in a car or on a crowded desk.

Usage tips

For a morning commute, fill the tumbler, choose the flip opening or insert a straw, and keep it standing in the cup holder. At a desk, the straw can make it easier to take a quick sip without removing the lid. After use, the product is listed as dishwasher-safe, follow any care directions that come with the tumbler, since more detailed cleaning instructions aren’t provided here.

You may want to skip it if you need a container you can confidently pack sideways or upside down. The leak warning is a meaningful trade-off, even though the product is described as leakproof. If spill resistance in a bag matters more than having a built-in straw and flip lid, a bottle with a fully sealed drinking opening is a better fit for that use.

Before you decide

Does it include straws? Yes. The description lists two reusable straight straws.

Can you drink without a straw? Yes. The flip opening allows direct sipping from the lid.

Is it safe to carry upside down? The listing warns that the straw connection may leak when the tumbler is inverted, so keep it upright.

Buying verdict

This BJPKPK coffee tumbler is worth considering for upright, everyday sipping when a straw, flip lid, and tapered car-cup-holder design are useful. Its stainless steel construction and vacuum insulation are appealing features, but the stated leak risk around the straw connection makes it a poor match for careless bag storage or frequent tipping. Choose it for a commute or desk routine where it can stay vertical, choose a more securely sealed format if spill protection is the priority.
