The PET bottle became Ulrica's comment after Björn Kjelltoft at his graduation exhibition at Konstfack painted Ulrica's pattern on PET bottles and cardboard plates. Did a designer have a patent for universal symbols? Instead of a lawsuit, Ulrica took back control of her eyes and tulips and let them adorn PET bottles in glass in limited edition.The bottles became very popular and came to be used as the perfect unique and always filled water bottle. Now the PET bottels are back in the tribute collection for Ulrica Hydman-Valltien.
