Near-monopoly in rubber stoppers/elastomers for biologics. Every GLP-1 pen needs one.

Near-monopoly position in rubber stoppers and elastomers for biologics. Every Wegovy, every Mounjaro, every monoclonal antibody is sealed by a West stopper. The most boring, most durable name in this entire sector. Lower beta than Stevanato.
