At TERASYNA™, we aim to provide customers with a clear and reliable delivery experience.

TERASYNA™ is owned and operated by Xuzhou Peiya Intelligent Technology Co., Ltd., which manages this official online store and coordinates order processing, customer communication, and shipping-related support.

This Shipping Policy explains how orders for our children's puzzles and included accessories are processed, shipped, tracked, and supported after purchase.

After an order is submitted, our team begins preparing the order for shipment.

We review the order information and arrange fulfillment procedures so that your selected puzzles, themes, variants, and included components are prepared for dispatch.

Orders are generally processed through our fulfillment system as quickly as possible. Processing time may vary depending on product availability, order volume, holidays, or other operational factors.

TERASYNA™ focuses on efficient order handling and shipment preparation.

Once an order has completed processing, it will be arranged for delivery through an appropriate shipping service.

We work to improve our fulfillment process and provide customers with a smooth delivery experience.

Delivery time may vary depending on the destination, transportation conditions, and other circumstances outside our direct control.

Please ensure that the shipping information provided during checkout is accurate to help avoid unnecessary delivery issues.

TERASYNA™ works with delivery partners to provide shipping services. The available shipping method may depend on:

• Delivery destination

Shipping arrangements are selected to support a reliable delivery experience.

After an order has been shipped, you may receive shipment information containing available tracking details.

You can use these details to follow your delivery progress. Please allow reasonable time for tracking information to update after shipment confirmation.
