Learn how to install, use, and clean the MiiR Press-fit Straw Lid, plus compatibility tips and common mistakes to avoid.
Quick answer
To use the MiiR Press-fit Straw Lid, simply press it firmly onto a compatible MiiR tumbler or camp cup, then sip through the flexible silicone straw. Remember, it's not leakproof, so treat it as a spill-resistant lid for cold drinks only.
Why the Press-fit Straw Lid is a great choice
The MiiR Press-fit Straw Lid is designed for smooth sipping on the go. Its flexible silicone straw stays quietly in place and washes easily, making it a convenient option for daily hydration. It fits most MiiR Tumblers, all Camp Cups, and Lowball & Highball glasses, so you can use one lid across multiple MiiR vessels.
However, this lid is not leakproof. If you plan to toss your bottle into a bag, you'll want to choose a leakproof lid instead. The Press-fit Straw Lid is best for desk use, car rides, or anywhere spills are less likely to be a problem.
Compatibility and limitations
Before using the lid, confirm it fits your MiiR vessel. It works with most MiiR Tumblers, all Camp Cups, and Lowball & Highball. The straw trim length varies by cup size: for Camp Cups, the 12oz uses a 3.91in/99mm straw, and the 16oz uses a 4.9in/124mm straw. If you're using a different MiiR cup, check the straw length to ensure it reaches the bottom.
Also, the Press-fit Straw Lid is not intended for hot beverages. The silicone straw and lid material are not designed for high temperatures, so stick to cold or room-temperature drinks.
How to use the MiiR Press-fit Straw Lid
- Check compatibility: Ensure your MiiR vessel is compatible: most MiiR Tumblers, all Camp Cups, and Lowball & Highball. If you're using a Camp Cup, verify the straw length matches your cup size (12oz: 3.91in/99mm, 16oz: 4.9in/124mm). Using the wrong straw length may leave the straw too short to reach the bottom, or too long and uncomfortable to sip.
- Press the lid firmly onto your cup: Align the lid with the rim and press down evenly around the edges until it snaps into place. The press-fit design creates a snug fit, but it's not leakproof. A common mistake is pressing only on one side, which can cause the lid to sit crooked and increase the risk of spills.
- Sip and enjoy: Use the flexible silicone straw to sip your cold beverage. The straw stays in place, so you can drink hands-free while driving or working. Remember: this lid is not leakproof, so avoid tipping it over in your bag.
- Clean after each use: Rinse the lid and straw under warm water or place them in the dishwasher. The silicone straw washes easily, promoting reusability. Check that the straw is fully dry before reassembling to prevent mold or odor buildup.
