When buying a football, read the size, weight, surface and intended use as well as the product name. The word Professional alone does not establish a particular certification or suitability for every surface.
Quick answer
The KX Professional Match Ball TOP-2 description specifies size 5, a weight of 430–440 g and hand-stitched construction. Its intended use is described mainly as softer surfaces. These details do not establish FIFA certification or equal durability on hard surfaces.

- Weight: 430–440 g.

Match specifications and certification are different checks
IFAB defines requirements for ball dimensions, weight and pressure. Some official competitions also require particular FIFA quality marks. A size 5 label does not prove FIFA QUALITY or FIFA QUALITY PRO certification. For competition use, check the organiser's rules and the ball's verifiable quality mark.
Inflation and the first check
Use the pressure stated on the ball or in the manufacturer's instructions and measure it with a pressure gauge. The product description asks users to use a suitable inflation needle, lubricate the valve and check the ball for 24 hours after the first inflation. Do not force the valve. Read the product-specific instructions and current sales conditions before ordering.
Care after use
Remove surface dirt gently and dry the ball according to the model's care instructions. Do not leave it next to a heat source or in direct sunlight. Check stitching, the valve and air loss regularly. The product information does not support promises that every shot will reach its target, that the ball will remain unchanged for years or that performance will be identical on every surface.
