Agreement and site content
By accessing the website or placing an order, you agree to these terms. The site presents engineering concepts, research, artwork, creative works, portfolio materials, and a small collectibles marketplace. Portfolio materials are for general informational purposes; descriptions of concepts do not guarantee performance, investment results, or commercial availability.
Marketplace purchases
Products are offered subject to availability, and photographs and descriptions should be reviewed before ordering. Listed marketplace items include free shipping unless the listing clearly states otherwise. Displayed prices are in U.S. dollars. Your purchase is subject to successful payment authorization and order verification.
All sales final — no voluntary returns
All sales are final. No voluntary returns or exchanges are accepted for buyer’s remorse, a change of mind, or an unwanted purchase. This policy does not exclude remedies required by applicable law or protections that may apply through PayPal or another payment provider.
If an item arrives damaged, is incorrect, or is materially not as described, email [email protected] promptly with your order number and supporting photographs. We will review the issue in accordance with applicable law and payment-provider requirements.
Order cancellations and payment
You may leave checkout before paying. Once payment has been captured, cancellation requests are not guaranteed; contact support immediately with the order number. PayPal processes payment and may administer any eligible disputes or buyer-protection claims under its own policies. No provision here limits rights that cannot legally be waived.
Shipping and delivery
Shipping destinations and available delivery services are determined during checkout and order handling. Shipping timeframes are estimates rather than guarantees unless explicitly stated otherwise. If your address needs correction, contact us promptly with your order number; changes cannot be guaranteed after dispatch.
Accounts and acceptable use
Provide accurate information and keep your login credentials private. You are responsible for activity under your account except where prohibited by law. Do not attempt unauthorized access, abuse of the service, automated disruption, fraud, or misuse of the website or its content.
Ownership and use of materials
Unless otherwise indicated, original site content, designs, text, research presentations, and artwork belong to their respective rights holders. Browsing does not transfer intellectual-property rights. Referenced trademarks and third-party material belong to their owners. Seek written permission before reproducing proprietary content.
Requests, proposals and investments
Messages and investment inquiries are invitations for discussion only. Submitting an idea or proposal does not establish a partnership, employment, licensing agreement, investment transaction, confidentiality obligation, or other formal relationship without a separate written agreement. Nothing on this website constitutes a securities offering or professional investment advice.
Limitations and changes
The website and its portfolio content are offered as available, subject to limits and consumer protections imposed by law. We may update offerings and these terms. Disclaimers and limitations apply only to the extent permitted by applicable law. For questions email [email protected].
