A round elastic, made in France, composition: 57% ED, 43% PES

Further information:

• 57% ED: - Elastodiene (a type of rubber), which is a synthetic elastomer used for its elastic properties.
• 43% PES: This stands for Polyester (PES), a synthetic fiber known for its strength, durability, and resistance to stretching or shrinking.

Together, this blend of materials provides the elastic with a good balance of stretchability (from the Elastodiene) and strength/structure (from the Polyester), making it suitable for applications like hats.
