MAR Bio Drain 12 Sticks Enzyme Sink Shower Odour Eliminator One a month for full year; kitchen sinks, basins and showers; drop in leave, no pouring or mess

A FULL YEAR IN ONE PACK — Twelve sticks, one a month, so a single pack covers a drain for the whole year without reordering. STOPS DRAINS SMELLING — Helps tackle the build-up that causes bad smells rising from the plug hole, keeping kitchens and bathrooms fresher between deep cleans. BIO FORMULA — Works on the residue inside the pipe rather than blasting through it with harsh chemicals, so it's gentler on your pipework. DROP IN AND FORGET — Push one stick into the plug hole once a month. No pouring, no measuring, no gloves and nothing to rinse away. KEEPS DRAINS RUNNING FREELY — Regular use helps prevent the gradual build-up that leads to slow-running drains. Keep out of reach of children and pets, and wash hands after handling. Ships in the manufacturer's packaging and branding.
