Ball Care

How to maintain the ball’s condition

A word of caution when inflating the ball

Please always moisten the inflating needle with Glycerin (NDLSC) before inserting it into the valve.

Item Name: Glycerin (NDLSC: for smoothing the inflating needle)

Please inflate the ball to the correct pressure.

Adjust the air pressure of the ball using an air gauge AG500/AG1000 to the appropriate internal pressure.

Item Name: Digital Gauge (AG500/AG1000)
Corresponding to various Air Pressure Units
The Upper Limit: (138 kPa, 1.4 kgf/cm2, 1.4 bar, 20 psi)

  • Please inflate the ball to the correct pressure
  • Adjust the air pressure of the ball using an air gauge AG500/AG1000 to the correct pressure
  • Regulation of the internal pressure is the secret to keeping the ball at optimum softness with the best rebounding performance and to ensure its durability.
  • The recommended internal pressure is printed around the valve of a ball.

Ball’s classification by process of manufacture

MIKASA balls are categorized into the following four groups by process of manufacture.

Please be careful on the maintenance methods because the methods are different depending on the process of manufacture.

  • 1. Laminated ball (New material type)

    This is a type of a ball of which the panels are laminated onto ball’s carcass.The improved soft surface material is used for lamination to generate the soft feeling which we never had before by conventional, artificial or natural leather process.

    ▼ maintenance method
  • 2. Laminated ball (Synthetic leather / Natural leather type)

    This is a type of a ball of which the panels are laminated onto ball’s carcass. Mostly, the panels are used for volleyball and basketball.

    ▼ maintenance method
  • 3. Stitched ball (Hand-stitched/ Machine-stitched)

    This is a type of a ball of which each panel is stitched over the ball’s carcass. Stitched balls are categorized into hand-stitched and machine-stitched.

    ▼ maintenance method
  • 4. Quality Rubber ball(Others)

    The quality rubber is covered over the balls carcass. The quality rubber balls are categorized into soft foam rubber and normal rubber according to the hardness of the rubber.

Maintenance method

1. The maintenance method for laminated ball (New material type)

Ball care after using ball

  • Please wipe the surface of the ball with a soft cloth.
  • If you are unable to remove dirt easily, please wipe the ball with a moistened cloth.
  • If you are unable to remove dirt with water, please wipe the ball with a cloth moistened with a water-diluted mild detergent.
  • If you use a mild detergent to clean the ball, please wipe off any remaining detergent thoroughly to ensure that it does not remain on the ball surface (detergent may cause ball discoloration)
  • If you use water to clean the ball, please wipe the ball afterwards with a dry cloth.
  • Please dry the ball out of direct sunlight in a well-ventilated place.
  • If the ball has been soaked in rain, please wipe away moisture and dirt using a cloth, then dry the ball out of direct sunlight in a well-ventilated place.
  • Please do not wipe the ball with solvents such as benzene. (This may damage the cover material.)

When the ball gets wet..

Panels for a laminated ball are bonded by glue on the ball’s carcass.
The excessive moisture and heat to the ball brings a decrease of adhesion force, and the panels may peel off or may have discoloration.

  • If you use water to clean the ball, please wipe the ball afterwards with a dry cloth.
  • Please dry the ball out of direct sunlight in a well-ventilated place.
  • Please do not use the dryer to dry the ball out.

Precaution

  • Please store and carry the ball with adequate air pressure because the storage and carriage by deflated conditions may cause wrinkles on the ball surface.
  • Please avoid leaving balls in a place that is exposed to direct sunlight.
  • Please avoid storing balls in hot or humid places.
  • Please store balls in a well-ventilated place.
