About This

【PROTECT WOOD & TONE】 — Designed for 4/4 and 3/4 cellos. This humidifier maintains ideal moisture levels to prevent wood cracking, panel warping, and glue failure in dry winter or heated rooms, preserving your instrument’s rich acoustic resonance.
【DRIP-RESISTANT DESIGN】 — Features a high-absorption sponge core to hold moisture effectively. Precision-drilled holes release vapor evenly, humidifying the interior safely without affecting delicate cello varnish or wood finishes.
【SECURE F-HOLE FIT】 — Engineered with a 12.99" (33cm) length and 0.59" (1.5cm) diameter to slide easily into standard F-holes. The 0.98" (2.5cm) cap ensures the tube stays in place and won't fall into the instrument body.
【SIMPLE MAINTENANCE】 — Just soak in water, squeeze out excess liquid, and wipe the exterior dry before inserting. The durable milky white rubber tube allows for easy hygiene checks and long-term reuse for consistent instrument care and maintenance.
【ESSENTIAL CELLO CARE】 — A reliable tool for musicians in dry climates or during travel. This moisturizer provides internal humidity control, making it an ideal gift for cellists to protect their 4/4 or 3/4 size instruments.
