Think about what you’re filling and how you’ll use it.

• 2 oz (about 60 mL): Handy for single shots, extracts, and quick tasters.
• 3.4 oz (100 mL): Popular for travel-sized kits or slightly larger samples.
• 4 oz (about 120 mL): Good for mini juices, dressings, or gifting favors.
• Mouth opening: Wide mouths help with thicker blends and easier cleaning; standard mouths are space-saving.
• Pack count: Bulk packs can be useful for batching or events.
• Travel note: If flying, many travelers prefer 100 mL or smaller, but policies vary—always check your airline’s guidelines.

On Walmart.com, you can filter by size, material, and pack count for a quicker match.

Both can work—choose based on your priorities.

• Glass: Resists stains and odors, often dishwasher-friendly, and fits oils or citrus well. It’s heavier and breakable, so consider storage and handling.
• Plastic: Lightweight and great for on-the-go or events. Look for listings that note BPA-free materials and whether they’re top-rack dishwasher safe. Over time, plastic may scratch or retain odors.
• Lids and seals: Leak-resistant caps matter more than material; check if the product includes gaskets or liners.
• Care: Always follow the care notes in the product description to help extend the bottle’s lifespan.

Freezing can be fine with the right bottle and a few precautions.

• Check the listing: Use bottles labeled freezer-safe.
• Leave headspace: Keep about 10–20% empty to allow liquids to expand.
• Cool first: Let hot liquids cool before filling to reduce stress on the bottle.
• Avoid sudden changes: Even with borosilicate glass (if listed), avoid quick temperature swings.
• Thaw gently: Defrost in the fridge or cool water; recheck cap tightness afterward.
• Skip carbonation: Fizzy liquids can build pressure and loosen lids.

Results can vary by bottle design, so start with a small test batch.

A consistent, gentle routine helps keep small bottles fresh.

• Before first use: Wash bottles, caps, and funnels with warm, soapy water.
• Daily cleaning: Use a bottle brush for corners; if dishwasher-safe is noted, place bottles top rack and caps on a secure holder.
• Deodorize: A baking soda soak or diluted vinegar rinse can help with lingering smells; rinse thoroughly.
• Dry completely: Air-dry upside down; store with caps off to prevent trapped moisture.
• Mind the material: Avoid high heat on plastic unless specified; limit thermal shock for glass.
• Inspect seals: Check gaskets and threads for wear to help maintain a good seal.

You’ve got a few easy ways to find replacements.

• Check your order page: The listing often notes cap size and compatible accessories.
• Search on Walmart.com: Look for “replacement caps” or “mini funnels,” and filter by size and material to narrow options.
• Multipacks: Some accessory sets include spare lids, liners, and funnels, which can be convenient for batching.
• Contact the seller: Through your Walmart account, you can ask about compatible parts for your specific bottle.
• Pickup or delivery: Where available, choose pickup or delivery for quick turnaround.

Verifying sizes (e.g., neck diameter) before you buy can help ensure a better fit.
