Tote Anello Calf NocciolaDESCRIPTION CORIU 2021 Spring Summer Collection. This is a tote bag representative of CORIU with a brass fastener. The calf leather used is a traditional leather manufacturing method that has been handed down in Italy for 1000 years. The leather is tanned only with the astringent of the plant and is given a rich texture by adding plenty of oil and fats. The brass fastener is fixed through a buttonhole like hole, making it durable and easy to use.
