2. Eligibility and lawful use
You must have the legal capacity to enter into a purchase agreement in your jurisdiction. You agree to purchase, import, possess and use products only where lawful and only for lawful purposes. You are responsible for checking local laws, import rules and any destination restrictions before ordering.
3. Product information
We work to keep product descriptions, specifications, compatibility information, images and pricing accurate. Minor variations in color, packaging or non-material details may occur. Product images are illustrative and screen settings may affect how colors appear. If a material listing error is discovered, we may correct it and contact you before fulfillment.
4. Orders and acceptance
An order confirmation acknowledges receipt of your order but does not guarantee acceptance. An order is accepted when it is dispatched. We may request additional information, limit quantities, reject or cancel an order for stock, pricing, payment, compliance, destination or fraud-prevention reasons. If a paid order is canceled before shipment, the affected amount will be refunded to the original payment method.

Prices are shown in the currency selected on the website. Shipping, taxes, duties and other charges are shown at checkout when available or may be collected by destination authorities. You authorize us and our payment providers to charge the amount displayed when you place the order.
6. Shipping
Order processing, tracking, delivery estimates, customs responsibilities and delay procedures are described in our Shipping Policy. Delivery dates are estimates unless expressly stated otherwise.
7. Returns and refunds
Return eligibility, required condition, damaged or incorrect items, return shipping and refund timing are governed by our Refund & Return Policy. Please contact us before sending any product back so that we can provide return instructions.
