Who Are we ?
École de l'Ongle Suisse is the professional shop founded in Martigny by Nathalie Costantini, an international master educator. For over ten years she has selected and distributed the brands she genuinely uses and recommends, Jana Nails, Staleks, NKF and other professional references. Buying here isn't ordering from just any reseller: it's getting field-tested products with advice from a team that knows the craft. Want to train or upskill? Our courses are now delivered by our ASC – Aesthetic Swiss Concept centre in Martigny.
