Certa focuses on simple natural swaps for products we use every day, from toothbrushes to kitchen essentials. Our products are designed with natural materials such as bamboo, natural bristles, loofah, sisal, and coconut fibers.

Our products are created as natural alternatives to common plastic and synthetic everyday items. For exact materials, we recommend checking each product description.

Certa toothbrushes use 100% natural bristles made from either horse hair or boar hair, paired with a smooth bamboo handle. We do not use nylon or plastic bristles.

Natural bristle toothbrushes are not vegan, whether made from boar or horse hair. Boar-bristle brushes are not halal. Customers who prefer a halal option can choose the horse-bristle toothbrush.

Rinse the bristles well after brushing, shake off excess water, and store the brush upright in an open holder to dry completely. Avoid storing it in closed or damp containers.

Your loofah sponge may arrive flat. Simply soak it in water for a few minutes until it expands, then use it like a regular dish sponge for washing dishes, cups, and kitchen surfaces.

Rinse your kitchen products well after each use, shake off excess water, and let them dry fully in an open, airy place. Avoid leaving them sitting in water or in closed damp areas.

Replace your toothbrush every 2–3 months, or earlier if the bristles begin to fray. For kitchen products, replace them once they become worn out, damaged, start to smell, or no longer clean effectively.
