alvencrest.com is owned and operated by Shanghai Jiduiyu Network Technology Co., Ltd. By using the store or placing an order, you agree to these Terms and applicable store policies. If you do not agree, do not submit an order.

You must be legally capable of entering a binding agreement. If you have not reached the applicable age of majority, use the store only with the involvement and consent of a parent or legal guardian.

You are responsible for accurate account information and for maintaining the confidentiality of login credentials. Notify us promptly if you believe an account has been accessed without authorization.

We make reasonable efforts to present product descriptions, photographs, dimensions, materials, prices, and availability accurately. Minor color or appearance differences may result from lighting, screen settings, material characteristics, or manufacturing batches.

Age recommendations, care instructions, and safety information shown on product pages should be reviewed before purchase and use.

Submitting an order is an offer to purchase. An automated confirmation acknowledges receipt but does not necessarily constitute final acceptance. We may decline or cancel an order for payment failure, suspected fraud, pricing error, inventory unavailability, shipping restriction, or other legitimate reason. If payment was captured for a canceled order, an appropriate refund will be issued.

Prices are displayed in U.S. dollars unless another currency is shown. Product prices, discounts, shipping, and applicable taxes are displayed before payment. Payment is subject to authorization by the relevant provider.

Orders are generally processed within 2-4 business days, with up to 5 business days during busy periods. Standard U.S. transit is generally estimated at 10-15 business days after dispatch. Estimates are not guaranteed arrival dates. See our Shipping Policy for details.

Eligible products may be returned within 30 calendar days after confirmed delivery, subject to our Return & Refund Policy. Authorization is required before shipping a return. No restocking fee is charged for an approved return.

Report damaged, defective, incomplete, or incorrect orders within 7 calendar days after delivery and provide requested evidence. If an error attributable to us is confirmed, we may provide replacement, refund, reshipment, return, or another reasonable solution.

Contact us as soon as possible. Changes or cancellations cannot be guaranteed after fulfillment, packaging, or shipment preparation has started. No cancellation fee is charged for an order successfully canceled before fulfillment.

Discounts and promotions are subject to stated dates, purchase requirements, product exclusions, availability, and combination restrictions. They have no cash value unless required by law.

Follow all instructions, warnings, care guidance, and age recommendations. Adult supervision should be provided where appropriate. Stop using a product if damaged or if continued use may be unsafe. Product information is not medical advice.

We may limit quantities or reject orders that reasonably appear intended for unauthorized resale, commercial redistribution, or misuse of promotions.

Store branding, graphics, photographs, copy, designs, layouts, and original content are owned by or licensed to the store operator and may not be copied, modified, reproduced, or commercially exploited without authorization, except as permitted by law.

Content you submit must be accurate, lawful, relevant, and must not infringe another person's rights. You grant us permission to use submitted content for store operation, customer service, and marketing where permitted. We may moderate or remove unlawful, abusive, misleading, or irrelevant content.

• Use the store for unlawful, fraudulent, abusive, or harmful activity.
• Submit false, misleading, or unauthorized information.
• Interfere with website security, functionality, or other users.
• Scrape, harvest, or collect information without authorization.
• Infringe intellectual property, privacy, or other legal rights.

The store uses Shopify and may rely on payment, shipping, analytics, and other providers. Third-party services are governed by their own terms and policies.

We are not responsible for delay or failure caused by events outside reasonable control, including carrier disruption, severe weather, customs delay, network failure, labor disruption, government action, or other extraordinary events.

To the fullest extent permitted by law, the website and services are provided without warranties beyond those expressly stated or legally required. We are not liable for indirect, incidental, special, or consequential loss where such exclusion is permitted. Nothing excludes liability that cannot lawfully be excluded.

These Terms are governed by applicable law, without depriving consumers of mandatory protections available in their place of residence. Please contact us first so we can attempt to resolve concerns in good faith.

If any provision is unenforceable, the remaining provisions remain effective. Failure to enforce a provision is not a waiver of the right to enforce it later.

We may update these Terms when services, practices, or legal requirements change. The version posted when an order is placed will generally govern that transaction, to the extent permitted by law.
