The set consists of 3 different corner lifters with different blade lengths and are made of one piece. They are comfortable to hold due to the fluted structure. The ends of the Eckheber are bent accordingly and you can depending on which side one works to change the curvature, therefore there are also double probes. The ends are also to be able to scrape something sharp to remove excess skin, etc.. They can be used in versatile pedicure area and I am so far very pleased with the quality.
