When matching vending machine capsules to a gumball or bulk toy machine, size and shape matter.

• 1.1-inch acorn or round capsules are common for classic toy setups.
• 1.26–1.3-inch capsules fit machines adjusted for slightly larger prizes.
• 2-inch capsules are for machines with 2-inch wheels/chutes.

Check your machine’s coin wheel and chute opening; many manufacturers list compatible sizes in their manuals. On Walmart, confirm the capsule’s diameter (inches) and shape in the product details. Trying a small pack first can help you verify the fit. Avoid forcing capsules through a mechanism, as compatibility can vary by model and condition.

Choosing the right vending machine capsule starts with your use case and measurements.

• For most bulk toy machines: 1.1-inch capsules (acorn or round).
• For slightly bigger trinkets: 1.26–1.3-inch capsules.
• For large prizes/displays: 2-inch or even 3.9-inch (100 mm) capsules.

Measure the items you plan to insert and compare to the capsule’s listed inner/outer diameter. If you’re using a machine, match the capsule size to the machine’s wheel/chute specs. On Walmart, filter by size and review the product description for exact dimensions and pack counts. Results can vary by machine and item shape, so testing a small batch first can be helpful.

Round and acorn vending machine capsules behave a bit differently.

• Acorn capsules (dome top + flat base) tend to feed smoothly in many bulk dispensers and won’t roll away as easily when dispensed.
• Round capsules offer a uniform sphere that can maximize internal space for certain prize shapes and provides a classic look.

Some machines are tuned for one style over the other, so check your dispenser’s guidance and the capsule’s shape in the listing. Both styles typically snap closed; avoid overfilling to keep the halves securely joined. For party favors or classroom rewards, either shape can work—pick the look and capacity that suit your items.

You’ll find both options on this page—empty capsules and capsules prefilled with small toys.

• Empty packs are labeled “empty,” “clear,” or “fillable,” often in 1.1-inch to 2-inch sizes.
• Prefilled packs note toys inside, with phrases like “with toys,” “assortment,” or “styles may vary.”

Check the title and product description for size, color (clear, frosty, assorted), and count (50, 100, 150, 250, etc.). If you’re matching a machine, verify the capsule diameter; if you’re planning party favors, consider how many guests you have and choose a pack size accordingly. Availability and toy styles can vary, so reviewing photos and details before checkout is a good idea.

Beyond standard 1.1–1.3-inch toy capsules, there are larger options for projects and displays.

• 2-inch round or acorn capsules suit bigger trinkets and machines designed for 2-inch prizes.
• 3.9-inch (100 mm) clear capsules are popular for displays, prize or egg hunts, and even forming bath bomb molds.

Review the listed diameter and closure style to ensure your items fit comfortably without stressing the seam. Larger capsules aren’t typically intended for small coin-operated machines, so plan for hand distribution or display use. On Walmart, you can browse by size and pack count to align with your project needs.
