Two different sponges, a blue and a grey one, compose the set needed to work with Ergo
The sponges designed for Ergo are manufactured from two different materials to meet the needs of the operator. The blue one is used to organize and clean the hand files, the grey one instead is designed to clean the blades of rotary files in motion without collecting residues and especially without wrapping and damaging the sponge itself.
The sponges are autoclavable but are intended for single use.
