Konokyo Insulated Tumbler 34 oz

The slim base is designed to fit in most cup holders, making this 34 oz tumbler easier to bring along in the car than a wide, straight-sided cup. Its double-wall vacuum insulation is rated to keep drinks cold for up to 8 hours or hot for up to 6 hours.

The screw-on lid gives you two ways to drink: use the flip lid for hot beverages or add a straw for cold ones. Two straws and an extra straw seal are included.

If you prioritize a cup-holder-friendly shape and a straw option, this design covers both, if you prefer a simpler bottle with fewer lid parts, its two-way lid may feel like more than you need.

Where it shines

This tumbler is built for carrying coffee, water, or iced drinks through a commute or a busy day. Picture keeping it in a car cup holder and sipping cold water through the straw between stops, then using the flip lid when you fill it with coffee. The tapered base is intended to fit most cup holders, though that wording does not guarantee a fit in every vehicle.

The 18/8 stainless steel body and double-wall vacuum insulation give it a broader use range than a basic, uninsulated cup. The exterior is designed to resist condensation, so it is less likely to leave a wet ring on a desk and should feel easier to grip when cold. The listed insulation times are limits to keep in mind if your main concern is holding a drink’s temperature well beyond a typical outing.

Highlights

The 2-in-1 screw-on lid is the main convenience feature: sip hot drinks through the flip lid, or use a straw for cold beverages on the go. The product describes the lid as spill-proof, which suits carrying it around, but it is still worth treating a tumbler with a drinking lid differently from a sealed bottle when packing a bag. Without having tried it, the stated spill protection is best understood as a product feature, not a reason to assume it can be tossed around without risk.

You’ll appreciate it if you want a large-capacity tumbler with both straw and direct-sip options. It comes in blue, and the wide mouth is designed to make hand washing easier. The tumbler and accessories are BPA-free, and the product says they are safe to clean in a dishwasher. The extra straw seal is a useful spare part to have, especially if you regularly use the straw.

It may not suit you if you need a guaranteed fit for a particular cup holder, or if you want a fully leakproof container for carrying loose in a bag. No dimensions or weight are provided, so shoppers who need to judge its exact footprint or how heavy it will feel when full have limited information here.

Maintenance

Dishwasher cleaning is listed as safe for the tumbler and accessories. For hand washing, the wide mouth offers easier access than a narrow-neck bottle, and the removable straw and seal give you separate parts to clean. That added lid flexibility is convenient, but it also means more pieces to keep track of than with a basic one-piece drinking opening.

Should you buy it?

Choose this Konokyo tumbler if you want a 34 oz insulated cup for coffee, water, or iced drinks, and value a cup-holder-friendly base plus the choice of straw or flip-lid sipping. Its stated temperature window—up to 8 hours cold and up to 6 hours hot—makes it a practical fit for everyday trips rather than a clear pick for anyone who needs longer-lasting temperature retention. The missing dimensions also matter if you need a precise fit. For a desk, commute, or car ride where the two drinking styles are useful, it has a clear purpose, for bag-first carry or a simpler lid, a more securely sealed or less complex design may suit you better.
