You’ll find a wide range of toy marbles on Walmart.com, with options to suit games, builds, and decor. Selections often include:

• Bulk glass marbles: Assorted colors and finishes (clear, frosted, or cat’s eye).
• Glow-in-the-dark marbles: Great for night play and marble runs.
• Replacement sets: Sizes commonly listed (e.g., 14 mm, 16 mm ≈ 5/8", 18 mm ≈ 3/4") for classic board games.
• Decor marbles: For vases and aquariums.
• Marble runs: Building sets that include marbles; some feature glow pieces or special track elements.

To narrow your search, browse the Marbles and Marble Runs categories, check diameter and count, and review delivery or pickup options where available.

Match the marble to your game, build, or display by checking the diameter listed on the product page. Common sizes you’ll see include:

• ~10–12 mm: Small “peewee” or decorative uses (e.g., ~0.47" ≈ 12 mm).
• 14 mm: Frequently used for replacement game marbles.
• 16 mm: About 5/8"; a popular general-play size.
• 18 mm: About 3/4"; larger feel and visibility.

Tips:

• For board games, compare the diameter to your board’s holes.
• For marble runs, use the size recommended by the set.
• For decor, choose a size that fits your vase or display.

When in doubt, review product details and customer feedback to see how a size performs in similar uses.

Glow marbles can make tracks more exciting, especially in dim rooms. Many glow styles are designed to charge under light and then emit a soft glow, though brightness and duration can vary by material and lighting conditions.

• Check compatibility: Confirm the marble diameter matches your run’s recommended size.
• Charge first: Expose them to bright light before play for a better effect.
• Use in lower light: The glow is easier to see when the room is darker.
• Included or separate: Some runs come with glow marbles, while others may need add-ons.

As with any small parts, adult supervision is advisable and these items aren’t suitable for young children.

You can browse the Marbles category on Walmart.com for replacement sets in various colors and diameters. Many listings clearly note sizes (e.g., 14 mm, 16 mm ≈ 5/8", 18 mm ≈ 3/4") and counts suitable for classic games.

1. Measure or verify size: Check your game’s specs or measure a remaining marble.
2. Match colors/counts: Look for sets that provide the shades and quantities you need.
3. Consider bulk: Larger packs can help replenish multiple games.

Review product descriptions for diameter and quantity, and choose shipping or pickup options where available. This approach can help you get back to play without replacing the entire game.

Simple care can keep marbles looking their best and ready for play or display:

• Cleaning: Gently wash glass marbles with mild soap and warm water, rinse well, and dry with a soft cloth to help reduce water spots. Avoid harsh abrasives that could dull finishes.
• Glow finishes: If marbles have painted or glow coatings, brief cleaning and gentle drying are advisable.
• Storage: Use a lidded jar, pouch, or the original container to prevent chips and loss. Store away from small children.
• Decor use: For vases or aquariums, rinse marbles before placing and ensure they don’t obstruct pumps or filters.

Care needs can vary, so adjust based on how and where you use them.
