The use of a buffer and polishing paste was passed down to Bastien Gonzalez by his grandmother, as one  of her «little secrets» to get shiny nails without using nail polish. He updated this technique by creating (design and choice of materials) a natural horn buffer, handmade by one of the best horn craftsmen, whose ergonomic shape fits perfectly in the palm of the hand, allowing a quick and efficient rub on the nail. A chamois leather is fixed at the head of the buffer. The rubbing of the leather on the nails gives a sparkling and natural shine that lasts for several weeks. The association of the mother-of-pearl extract enhances the natural shine of the nail. The mother-of-pearl dust favours the vascularisation of the nail and gives it a subtle pink colour, enhanced by the shine of the polishing.
