Hans Jürgen Barthel

Cosna is an owner-managed company. 

Jürgen Barthel place the highest priority on delivering advice, quality, reliability, and on schedule.


In addition to the production, filling bottles, picking and packaging, we offer you a personal consultation about our range at our offices and compile the right collection for your business with you.

Innovative new developments are as much a part of our range of services as individual solutions for sales promotions - or put simply: good advice and a very flexible service. 

Ideas are Key

Original ideas and continuous research: at Cosna, a key issue at management level is creating new nail polishes.

For over twenty years we have put our creative experience and keen sense for detecting trends at the service of our customers.
