Melissa is a very famous Brazilian brand since 1983. All their shoes are made from a unique, patented plastic material called MELFLEX™, a form of PVC that provides improved elasticity, impermeability and resistance. It is hypoallergenic and 100% recyclable. Melissa plastic shoes are environmentally friendly as they can be easily disassembled and recycled. **CONDITION** The shoes are pre-owned. I purchased them at the Melissa store at original price. They are in excellent condition. They’re super flexible and comfortable to wear. Fully washed and cleaned prior to posting for sale.
