Great question—age ratings on each product page are the best guide. From there, think about grip, visibility, and play style.

• Younger swimmers (around 3–5): Choose larger, easy-to-grab pieces with bright colors. Bigger rings and chunky gems can be easier to spot and handle.
• Kids (5–8): Mix sinking rings and sticks for simple retrieval games that build confidence.
• Older kids and teens (8+): Try torpedo gliders and underwater passing balls for more challenge and skill-building.

Also consider set size, included storage bags, and where you’ll play. Adult supervision is recommended, and it’s wise to avoid small parts for younger kids. You can use filters by age and set size on Walmart.com to narrow choices.

It varies by item, and many sets include a mix. As a quick guide:

• Sinkers: Dive rings, sticks, gems, and coins are designed to sink for retrieval games.
• Gliders: Torpedo-style toys glide underwater and may slowly rise or hold depth for a bit.
• Floaters/targets: Some toys or markers float for surface games and scoring.

Check each product description for sink/float details and test new pieces in the shallow end first. Place toys away from drains and steps, and avoid throwing hard objects toward swimmers. Choosing high-visibility colors can help players spot items more easily under water.

Regular care helps your pool toys last longer and stay nicer to use.

1. Rinse: After chlorine or saltwater use, rinse with fresh water to help reduce residue.
2. Wash occasionally: Use mild soap and a soft cloth or sponge as needed. Avoid harsh chemicals.
3. Dry thoroughly: Air-dry out of direct sun; squeeze out water from fabric-covered toys.
4. Store smart: Use a ventilated container or the included mesh bag to help airflow.
5. Check wear: Periodically inspect for cracks, loose parts, or frayed fabric and retire items that look worn.

Limiting prolonged sun exposure can help reduce color fading over time.

Most pool diving toys on Walmart.com are made from plastics, rubbers, or fabric covers and are generally suitable for chlorinated or saltwater pools. To help maintain condition:

• Rinse after use: Fresh-water rinsing can help reduce chlorine or salt residue.
• Dry well: Air-dry to minimize moisture buildup in seams or fabric.
• Avoid rough surfaces: Decks and sharp edges can scuff softer materials.
• Expect some fading: UV and chemicals may affect color over time.

For specifics on materials and care, check each product’s description. Results can vary based on water chemistry and frequency of use, so simple maintenance goes a long way.

Replacement availability varies by item. Many diving toys are sold in multi-piece sets, and single components aren’t always offered separately. Here are a few tips:

• Check the product page: Some listings include add-on packs or compatible pieces.
• Match sizes and styles: Note ring diameters, gem sizes, or torpedo lengths for consistent gameplay.
• Consider mix-and-match: Extra rings, gems, or sticks from another set can keep games going.
• Order support: If something is missing out of the box, review your Walmart order details and support options.

Reading customer reviews and Q&A can also provide insight on compatibility with other sets.
