The purpose of this device is clear from the name: it is designed for convenient and safe cutting of lint from thin and rough-sensitive fabrics. Note that in some models, the
nozzle for delicate fabrics is standard, and the possibility of installing other devices is not provided.
The lid prevents contamination of the working nozzle of the remover and its contact with foreign objects. This piece of equipment is useful for storage and transportation. Of course, with proper packaging, the remover can be stored/transported without a lid — however, such packaging is not always available, and the lid, in turn, often allows you to do without improvised packaging at all.
