Key Advantages

-Compact 4-Inch Size for Controlled Painting
The 4-inch roller width is practical for smaller surfaces and narrow wall sections where a larger roller may be less convenient. It helps users focus on the intended painting area during localized repainting and touch-up work.

-Replaceable Sleeve for Compatible Roller Frames
The product is a roller refill rather than a complete roller assembly. It allows users to replace the painting sleeve while continuing to use an existing compatible roller frame and handle.

The RAINBOW name provides a clear reference when identifying this particular roller refill among other available models. It helps customers check the intended product when organizing painting supplies or purchasing replacement sleeves.

-Convenient Spare for Renovation and Maintenance

核心优点
