Ball capsules are small, two-piece plastic containers (usually round or oval) that snap together to hold tiny items.

• Common uses: vending machine prizes, party favors, scavenger hunts, and toy displays.
• Sizes: Popular options include ~32 mm (about 1.25 in), 1.3 in, and 2 in. Clear or transparent styles make the surprise visible; colored styles add pop.
• Shapes: Fully round or “acorn/oval” styles can affect what fits inside.

On Walmart.com, you can browse bulk packs, assorted colors, and different diameters to match your toys, crafts, or event needs.

These capsules are great for small surprises, but a few basics help keep playtime safe.

• Check age grading: Small parts can be a choking hazard. Keep away from children under 3 and supervise kids during play.
• Use for dry items: Most snap-closures aren’t designed for food, liquids, or perishable items.
• Inspect before use: Look for cracks or sharp edges and discard damaged pieces.
• Open carefully: Gently twist/pull halves apart to avoid pinched fingers.
• Care: Wipe with mild soap and water; dry thoroughly. Follow any product warnings and instructions in the listing.

They’re versatile little organizers and surprise holders you can customize for lots of occasions.

• Party favors: Fill with stickers, rings, or mini erasers for birthdays and holidays.
• Games & hunts: Create scavenger hunts or DIY advent countdowns with numbered capsules.
• Classroom rewards: Stock a treasure box with small prizes.
• Craft storage: Sort beads, buttons, or tiny screws by color or size.
• Surprise reveals: Hide slime portions, tiny figures, or notes.

Label with stickers, add confetti, or tie to ribbons for decor. Keep contents dry, and always keep small parts away from young children. If you’re done with them, consider reusing or check local guidance for disposal.

Match the capsule to what you want to put inside and how it’ll be used.

• Measure your item: Measure the widest point and add a little clearance so the halves can close without stress.
• Size guide (general): ~32 mm (about 1.25 in) fits tiny charms; 1.3 in suits small toys/erasers; 2 in handles slightly larger mini figures or squishies.
• Shape matters: Round vs. acorn/oval styles can change interior space.
• Vending compatibility: Check your machine’s diameter requirements before buying.

On Walmart.com, you can filter by diameter, pack count, and color assortment to find a good fit.

Most toy capsules use snap closures designed for quick open-and-close, not long-term sealing.

• Dry contents: They generally work well for small, dry items like charms, stickers, and trinkets.
• Not airtight or watertight: Liquids can leak, and moisture can get in over time.
• Short-term slime: Brief storage may be fine, but results can vary based on slime consistency and room temperature.
• Extra hold: If needed, a small piece of removable tape around the seam can add temporary security.
• Care tips: Avoid hot cars or direct sun, which can warp plastic; test one capsule with your contents before filling in bulk.
