Our premium 4-inch microfiber paint roller cover is engineered with high-quality lint-free white microfiber fabric, specially designed for smooth & semi-smooth wall, wood and concrete surfaces for DIY enthusiasts and professional industrial painters.

With consistent 10mm nap length, these mini roller sleeves deliver exceptional paint pickup and even paint laydown, minimizing messy splatters and stray lint to achieve streak-free uniform coating. The durable yellow inner plastic core snugly locks onto standard 6mm wire roller frames to avoid sliding during long-hour painting operations.

Compatible with latex, acrylic, oil paint, lacquer and various water-based coatings, widely used for interior ceiling, concrete wall refurbishment, furniture restoration, outdoor fence repainting and artistic artwork creation. Easy to rinse clean with water for repeated reuse, and we provide full OEM customization on size, color and packing to satisfy bulk wholesale orders.
