"mortar" is a collection created by Japanese crafts brand PULL + PUSH PRODUCTS. Inspired by the idea that every item that comprises life can be replaced by sensations, this collection aims to re-translate feelings into items by not treating mortar simply as a heavy and hard material, but interpreting it as one of the elements that stimulate human tactility. Launched in 2014, the collection is designed and produced by Nobuhiro Sato.
