It is made for compatibility with Vevor CM-50D and CM-80D cigar humidors and can be placed flat or contoured to fit the tank shape. The multi-layer 3D honeycomb mesh supports durable water retention while filtering impurities for consistent humidification. Its flexible material can be trimmed to fit different tank dimensions. Individually sealed packaging helps keep the pad clean until use.
