We offer distinct return processes based on the reason for your return. Please read the following sections carefully to understand your rights and the procedures for returning an item.
1. Your Right to Return Defective or Faulty Goods (6-Month Warranty)
In accordance with the Consumer Protection Act, if any product you receive is defective, faulty, unsafe, or of poor quality, you have 6 months from the date of delivery to return it. In such cases, you are entitled to a full refund, a replacement, or a repair of the item, at your choice. We will cover all costs associated with the return shipping for defective items.
To be eligible for a defective goods return:
- The return must be logged within 6 months of delivery.
- The item should be returned with all parts and original packaging where possible. We understand that discovering a defect may require opening the packaging or breaking a seal; returns for defective items will be accepted even if opened.
- Our inspection must confirm the issue was a manufacturing defect and not caused by customer misuse, improper installation, or normal wear and tear.
2. Your Right to a 'Cooling-Off' Return (Change of Mind)
In line with the Electronic Communications and Transactions Act for online purchases, you have a 7-day 'cooling-off' period. If you change your mind or ordered incorrectly, you have 7 days from the date of delivery to request a return for a refund or exchange.

- The item must be in its original, as-new, and resalable condition, unworn and unused.
- The item must be returned in its original packaging, with all original tags and accessories included. You may open the packaging to inspect the item, but it must be returned undamaged.
