JP Duo corks consist of a cylindrical body of agglomerated cork and two natural cork disks, one at each end.
The discs are produced from thin (slow-growing) cork, providing excellent sealing capacity and great elasticity.
They are stoppers with a homogeneous visual quality, chemically very stable and mechanically resistant, and present an exemplary performance in terms of sealing, as well as high organoleptic neutrality.
