Dunlop Intro (DYD) (12-Ball) Squash Box

The Intro (DYD)—often referred to as the "Dots Yield Difficulty" or Develop Your Drive series—is a specific line of squash balls designed for beginners and recreational players.

When you purchase a 12-Ball Squash Box of this type, you are typically getting a bulk supply of balls engineered to make the game more accessible and enjoyable while you're still mastering your swing.

1. Unlike the professional "Double Yellow Dot" balls, which are small and have very low bounce, the Intro ball is: 

• 12% Larger: The increased surface area makes it easier to track and strike.
• 40% More Hang-Time: It provides a significantly higher and more consistent bounce without needing the intense heat generated by professional-level rallies.

Standard squash balls require a rigorous "warm-up" period (hitting them hard against the wall for several minutes) to reach their optimal temperature and bounce. The Intro ball is designed to: 

• Bounce consistently from the first hit.
• Maintain its performance even in cooler court conditions.
• The Single Blue Dot: Most "Intro" or "Starter" balls are marked with a single blue dot.
• The Goal: It helps players develop the correct technique and "drive" (long straight shots) by giving them the time to get into position.

Buying a dozen pack is the standard for regular players for several reasons:

• Consistency: Having a fresh box ensures you aren't playing with a "dead" ball that has lost its grip or internal pressure.
• Cost-Efficiency: Bulk boxes are significantly cheaper per unit than buying individual canisters at a pro shop.
• Convenience: Squash balls do eventually break or lose their "fuzz" (becoming slippery). Having a box in your bag means you’re never sidelined mid-match.
