About Product

Zeroink Case is designed to support wireless charging, but it does not have magnetic attraction functionality. This is because the magnetic ring would interfere with the display effect of the e-ink screen.

Humid Environments：Avoid using or storing in water-vapor dense areas such as bathrooms, kitchens, or poolside to prevent the screen or circuit from malfunctioning due to moisture.
Water-Related Scenarios：Strictly prohibit using during water contact activities such as swimming, boating, or water sports.

The Zeroink Case features Quadrichrome™ E-Paper Technology with four encapsulated pigment layers (black, white, red, yellow). For optimal imaging:

Prioritize Warm Spectrum
Leverage red/yellow-dominant visuals for enhanced vibrancy
Activate Saturation Boost
Enable filters: > Blues | Gothic | Lomo < to intensify color dynamics
Avoid Cool Tones
Blue-purple hues exhibit reduced color fidelity due to spectral limitations

About Order

We support order fulfillment to multiple countries worldwide. However, due to limitations in local logistics infrastructure, we are currently unable to provide sales services to certain countries, primarily because logistics information in these regions cannot be tracked throughout the delivery process.We are continuously committed to expanding our shipping network. If your country is not currently within our service scope, please follow our official channels for the latest updates on available countries/regions.For specific shipping policies, feel free to contact our customer service team at any time.

If the product has functional defects, we will give you a full refund or resend you a new product.

If you place the wrong order, we can give you a partial refund or give you a larger discount to place a new order. Because the shipping fees and taxes for returning the product are already nearly half of the product’s selling price.
