Accessories : Intro

Switch it up, brighten it up, and keep your KeepCup going for years.

KeepCup accessories are designed to repair, refresh and restyle your favourite reusable — from sipper lids to straw lids, flip lids to bottle caps.

Mix colours, choose your fit and sip your way — sustainably, stylishly, again and again.

How do I choose the right lid for my KeepCup?

At KeepCup we have two ranges of products, the original range that has a press fit lid. These ranges have press fit sipper lids and straw lids with adjustments based on the cup material.

The modular Helix range is our screw fit range. The Commuter flip lid, Bottle lid and Helix Straw lid all fit the screw fit bases. They’re leak-resistant, easy to clean and made to mix and match.

Why are replacement parts expensive?

Replacement parts may seem costly compared to the cup itself, but there are several factors that influence the price. Every spare part — whether it’s a lid, plug, band, or glass component — goes through the same supply chain process as the full KeepCup. This includes manufacturing, quality control, warehousing, picking, packing, and shipping. Managing and storing many different parts across a global inventory adds complexity and cost, which is reflected in the price you pay for a single item.

Another factor is sustainability and durability. KeepCup doesn’t mass-produce throwaway items — each part is designed to be long-lasting, food-safe, and compatible with existing cups. Producing in smaller runs, with high standards, ensures your replacement part will perform and extend the life of your KeepCup rather than sending it to landfill.

To get the most value, we recommend bundling replacement parts with other items — such as a new KeepCup, gift, or accessory — to reach the free freight threshold. This way, you reduce the relative shipping cost and get more from your order.

Replacement parts are priced not just for the material itself but for the logistics, sustainability standards, and convenience of keeping your KeepCup in use for years. While it may seem like a small piece, the process behind delivering it to you is much bigger.
