Rainbow phone case made from flexible TPU outer and rigid PC inner frame with anti-scratch protection for Huawei P30, Mate20, Mate30 and NOVA series handsets, available in Black, Green, Orange or Pink colour options as a slim back cover style.
Rainbow Dual-Layer Phone Case with TPU and PC Construction for Huawei Models

This rainbow phone case provides a straightforward protective solution for a selection of Huawei smartphones. It uses a two-material build, pairing a flexible TPU outer layer with a more rigid polycarbonate (PC) inner frame, designed to help absorb impact from everyday knocks and scuffs. The case is made specifically for Huawei handsets, covering popular series like the P30, Mate20, Mate30, and NOVA lines. Available in Black, Green, Orange, or Pink, it offers a simple colour choice for users seeking a slim back cover that maintains the phone's original form factor without adding significant bulk or weight.
Features and Construction

This case's design centres on a practical two-part material construction intended for basic device protection. It is not a full bumper case but a rear cover that fits over the back of compatible Huawei phones.
Material and Build
The case is built using two distinct plastics. The outer layer is made from TPU (Thermoplastic Polyurethane), a material chosen for its flexibility and ability to help dampen minor impacts. This is fused with an inner layer or frame made from PC (Polycarbonate), a harder, more rigid plastic that provides structural support and can help resist bending or twisting. The combination aims to offer a balance between shock absorption and scratch resistance for the phone's back and sides.
Size and Practical Fit
The case is described as a back cover style, suggesting it is designed to be slim and form-fitting. It is made to be compatible with a specific list of Huawei models: P30, P30 Lite, P30 Pro, Mate20, Mate20 Pro, Mate30, Mate30 Pro, NOVA4E, NOVA5, and NOVA5Pro. This indicates a precise mould for each model variant to ensure proper alignment with camera lenses, ports, and buttons. The exact thickness or weight of the case is not specified, but the design intent is to provide protection without substantially increasing the phone's dimensions.
Uses and Placement

This case serves the primary function of protecting your Huawei phone during daily use. Its design is suited for general handling, placement in bags or pockets, and sitting on flat surfaces.
Event or Professional Use
For users in active environments or those who handle their phone frequently, the dual-material construction can help guard against scuffs, scratches, and minor drops. The rigid PC frame offers stability, while the flexible TPU can help absorb shock. The available colours—Black, Green, Orange, and Pink—allow for a degree of personal or brand expression in settings where a plain or coloured accessory is suitable.
Everyday Home Use
In everyday scenarios, this back cover provides a basic layer of defence against common hazards like placing the phone on rough surfaces, accidental knocks against tables, or exposure to dust and lint in pockets. The slim profile means it likely won't interfere with wireless charging pads designed for bare phones, though this should be verified with the specific charger model. The case is easy to install and remove for occasional cleaning.
Benefits and Buying Value

The value of this case lies in its straightforward approach to phone protection using a recognised material combination, tailored fit for Huawei models, and simple colour selection.
Reuse and Low Maintenance
The TPU and PC materials are generally wipe-clean with a damp cloth, requiring minimal upkeep. The case is durable enough for repeated installation and removal if needed, though over time the flexible TPU may lose some elasticity. Its compatibility with multiple Huawei series models means it could be a relevant accessory for users who upgrade within the same phone brand and model line.
Why Choose This Product
This case is a suitable option for Huawei phone owners looking for essential back and side protection without a bulky or complex design. The dual-layer TPU and PC build is a common and practical approach for mitigating everyday wear. The key differentiators are its confirmed compatibility with a wide range of specific Huawei models (P30, Mate20, Mate30, NOVA series) and the choice among four solid colours. It is a functional accessory focused on core protection rather than extra features like card holders or kickstands.
