It consists of a reusable frame and a replaceable roller cover.
Its main features are:-
1.Synthetic vs. Natural: Synthetic fibers (like polyester or nylon) suit water-based/latex paints, while natural fibers are ideal for oil-based paints, stains, or varnishes.
2.Woven vs. Knit: Knit covers hold more paint for rougher surfaces; woven covers provide a smoother finish for higher-sheen paints.
3.Microfiber: Delivers smooth coverage with low splatter and great paint release.
4.Foam (Sponge): Made from dense foam (open- or closed-cell) with no fabric fibers; ideal for high-gloss finishes on cabinets and trim without shedding fibers.
5.Features rubber-coated, textured, or ergonomic grips to reduce hand fatigue during extended painting sessions
