Yes — your payment is fully protected. All transactions on our website are processed through encrypted, PCI DSS Level 1–certified payment gateways, the highest global security standard for online payments.

QJ Global Group LLC, trading as Grimstrike, never sees or stores your full card number, CVV, or banking details. All sensitive payment data is encrypted end-to-end and handled exclusively by PCI-compliant third-party processors such as Shopify Payments, Apple Pay, Google Pay, and Shop Pay.

Depending on your bank, additional verification (such as 3D Secure or multi-factor authentication) may be required to ensure maximum protection.

Your privacy and security are always our top priority.

9. How do I choose the right size?

Each product page includes a detailed size guide, showing the specific measurements for that item. Because sizes can vary between products, we strongly recommend checking the size chart on the product page you are viewing before placing an order.

If you’re unsure between two sizes or need help interpreting the measurements, you can always contact our support team at support@grimstrike.com. We’re happy to provide personalized sizing advice to help you choose the best fit.

10. Do you ship internationally?

We currently ship only within the United States.

11. Can I change or cancel my order?

Orders can be cancelled or adjusted only if they have not yet entered processing.

Once an order has begun processing, no changes or cancellations can be made.
This includes changes to:

  • items

  • sizes

  • colors

  • shipping address

  • payment details

If your order is already processing or has shipped, cancellation is no longer possible.
You may still use our 30-calendar-day return window as outlined in our Return & Refund Policy.

For urgent assistance, contact us immediately at support@grimstrike.com.

12. What if my package is delayed?

If your order is delayed more than 5 business days beyond the estimated delivery window, contact us for assistance.

13. What if my package is lost or stolen?

If your package is marked as delivered but you did not receive it, contact us within 5 days at support@grimstrike.com.

We will help investigate the issue with the carrier.
If the carrier confirms that the package is lost, we will provide either:

  • a replacement, or

  • a refund to the original payment method.

Packages that are incorrectly delivered due to an incomplete or wrong address entered at checkout are not covered, as customers are responsible for providing accurate shipping information.

14. My item arrived damaged — what now?

If your item arrives damaged, defective, or incorrect, contact us within 30 calendar days of delivery at support@grimstrike.com.

Please include:

  • your order number

  • clear photos of the item and packaging showing the issue

Once verified, we will offer:

  • a free replacement, or

  • a full refund to the original payment method.

Damaged/defective items are always eligible for a refund or replacement — even if they are normally non-returnable items under standard return conditions.
