Straw cover caps can be handy if you’re taking drinks on the go or sharing space with others.

• Cleaner sipping: They can help block dust, lint, and bugs—especially useful for outdoor use or gym bags.
• Fewer splashes: Plug-style caps may reduce minor sloshes when you’re walking or commuting.
• Hygiene between sips: Covering the straw between drinks can be a practical extra step.
• Personalization: Bright toppers make your cup easy to spot at gatherings.
• Reusable: Many options are washable and designed for repeated use.

Just check the cap style (slip-on vs. plug) and size range to match your straw. Results can vary with cup style and how you carry it.

“Straw toppers” are small accessories that go on (or in) a drinking straw.

• Names you’ll see: straw caps, straw covers, toppers, and plugs.
• What they do: Cover the opening or seal the straw to help keep out dust and limit splashes between sips.
• Styles: Decorative slip-on covers, sealing plugs, and tip sleeves for comfort.
• Materials: Commonly silicone or soft PVC; check product details for specifics.
• Sizes: Made for different diameters (for example, about 7–8 mm or around 10 mm).

Pick a style and diameter that match your straw and lid clearance so it opens and closes comfortably.

Straws can change how beverages contact your teeth, but effects vary.

• Potential benefit: Sipping through a straw may route liquid past front teeth, which could help minimize direct contact with certain drinks.
• It depends how you sip: If you swirl or hold liquid in your mouth, a straw may offer less benefit.
• Not a substitute: A straw isn’t a replacement for regular oral care.

For personalized guidance—especially if you have sensitivity or dental concerns—consider asking a dentist or hygienist. Choose what feels comfortable for you and use lids or straw caps to help manage spills.

You can shop a wide selection of straw caps on Walmart.com and in the Walmart app.

• Search terms: try “straw caps,” “straw toppers,” or “drinking straw covers.”
• Filter smart: narrow by straw diameter (mm), color, material, and set size.
• Check details: look for fit ranges (e.g., 7–8 mm or 9–11 mm) and care instructions.
• Get it your way: choose shipping, pickup, or delivery where available.

Product pages often include measurements and photos to help confirm compatibility with your cup and lid.

Getting the right fit is mostly about diameter and cap style.

1. Measure your straw: Use a ruler or caliper to gauge the outside diameter (OD). Common ranges include about 7–8 mm for standard straws and around 10 mm for wide straw tumblers.
2. Match the listing: Choose caps with a stated fit range that covers your straw’s OD.
3. Consider clearance: If your cup has a lid, make sure the topper won’t hit the lid when you drink.
4. Pick a function: Slip-on covers help block dust; plug-style caps can offer a tighter seal.

Review the product description and photos before you buy—fit can vary by brand and lid design.
