Côte Noire offers decorative home fragrance and floral products designed to bring colour and scent into interior spaces. Its range includes perfumed flowers and bouquets, such as roses, hydrangeas and seasonal arrangements, presented in vases, goblets and hatboxes. The flowers are handcrafted, set in a water-like gel and individually scented, with selected arrangements supplied with small bottles of fragrance. The brand also sells fragrance sprays, candles and home diffusers, including diffuser refills and gift sets.

Côte Noire’s collections feature varied styles and finishes, from Art Deco and Herringbone designs to crystal bouquets and signature-badge candles. Its diffuser products use absorbent reeds to release fragrance gradually, while the site describes some arrangements as having specially coated petals for a lifelike touch and appearance. Customers can shop new arrivals, browse collections and find selected items in a clearance section. The online store displays prices in euros and offers free delivery and a complimentary tote bag on orders over €99.
