This is a set of three soft filters for Hasselblad cameras. The set includes Softer I, Softer II, and Softer III. The filter diameter is 60mm. While there shouldn't be any issues, please understand that these are quite old, so they are recommended for those who understand this. The case is included, but the internal foam has deteriorated and has been removed. The filters will be wrapped in silk paper for shipping. Thank you for considering.
