Find out if the 170mm stainless steel straw fits your 20oz or 34oz bottle. We break down fit, material, and when to choose a different straw.
Quick answer
The 170mm stainless steel straw is designed to fit frank green 20oz/595ml and 34oz/1L Ceramic Reusable Bottles. If you own either size, it's a direct replacement; if you have a different bottle, check the straw length and lid opening before buying.
Why length matters more than you think
A straw that's too short leaves you tilting the bottle awkwardly; too long and it can poke through the lid or sit at an odd angle. The 170mm length is matched to the internal height of the 20oz and 34oz Ceramic Reusable Bottles, so it reaches the bottom without excess.
If you're using a different bottle, measure from the lid opening to the base and compare. A straw that's within a few millimetres of that measurement will usually work, but a significant difference means you should look for a dedicated replacement straw for your model.
Material and care trade-offs
This straw is made from food-grade 304 stainless steel, which is durable and dishwasher safe. Unlike silicone or plastic, it won't retain flavours or stain, but it's rigid and can be noisy against the bottle if you stir. It's also not suitable for hot drinks if you're using it with a ceramic bottle that's filled with coffee or tea—metal conducts heat, so take care.
The straw is easy to clean in the dishwasher, but a quick rinse after use helps prevent residue build-up inside. The product image is for display only; you may receive a silver or gold coloured straw, so don't rely on a specific colour match.
Decision rules for buying the 170mm straw
- You own a 20oz/595ml or 34oz/1L Ceramic Reusable Bottle: Buy this straw. It's the specified replacement and will fit without modification.
- You own a different frank green bottle size: Check the bottle's manual or product page for the recommended straw length. This 170mm straw may be too long or too short for other sizes. Measure your bottle's internal height before ordering.
- You want a specific straw colour: The straw comes in silver or gold at random. If colour matters, consider buying from a retailer that lets you choose or contact support before ordering. Colour is not selectable; plan accordingly.
- You need a straw for a non-frank green bottle: Measure the distance from the lid opening to the bottom of your bottle. If it's close to 170mm, this straw may work, but check the diameter of your lid's straw hole to ensure a secure fit. Compatibility is not guaranteed for other brands.
