66 X Pro

Step up your control with the Hundred 66 x Pro strings. Constructed from high-performance multi-filament nylon, these strings deliver professional-level precision and feel. The flexible profile cushions shots for careful placement while superior elasticity snaps the strings back into position, returning energy for controlled drives and lifts. Maintain consistent tension and durability set after set thanks to advanced construction. For players who value control above all else, 66 x Pro strings provide the touch, response, and reliability you need to take your game to the next level.

Orders are shipped via Standard Ground ($10, or free for orders over $75) or Expedited 2-Day service ($25). Expedited orders placed before 2 PM PST are processed the same day, while standard orders typically ship within 1–3 business days. Please note that shipping is strictly domestic; delivery to international addresses, US territories, PO boxes, or freight forwarding services is not available.

Returns are accepted within 30 days of purchase but must be in pristine, unused condition with all original tags attached. Specific strict guidelines apply: racquets must still have the plastic wrap on the handle, and shoes must be unworn and returned in their original box. You can initiate a return via your account or by WhatsApp (3319808562) to receive a UPS label, but please note that an $8 return shipping fee will be deducted from your refund unless the item is defective or incorrect.

Once your return arrives at the warehouse, it undergoes a 3–5 day inspection. If approved, the refund process typically takes an additional 10–15 business days. Items that fail inspection (e.g., used or missing tags) will be sent back to you without a refund. Currently, direct exchanges are only available for shoe sizes; for all other items, you must return the original and place a new order.
