Once your order leaves our warehouse, it is handled by a carrier that may provide tracking information until you receive sleep bra . The tracking information might be accessible from the logistics company website when it becomes available. If you have any further questions about the status of your order, you can contact our support team directly. Please note tracking information may not be available for up to 48 hours after an item is shipped from our warehouse. Tracking availability may vary depending on the type of item you purchased.

In order to expand the trade, Tengfei Technology Co., Ltd. has been always exploiting the international market to spread our high quality running bra. We will show you the running bra series that is most popular with customers. A wide range of product inspections were carried out for Tengfei Technology wearable technology clothing. In many cases, test standards such as color fastness tests go far beyond applicable national and international standards. The product has the ability to accept very high currents. Its low internal impedance minimizes energy loss and heat generation.

We are committed to achieving a balance between business development and the environment. We will seek a brand new approach to upgrade the production mode to achieve a non-pollutive and less energy consumption one.
