Rare Ngwenya Glass Pitcher Plant vases - excellent condition

PLEASE DISREGARD REFLECTIONS - SO DIFFICULT TO PHOTOGRAPH BUT IN PERFECT CONDITION. I CANNOT FIND OTHER NGWENYA GLASS ITEMS LIKE THESE - THEY LOOK LIKE PITCHER PLANTS AND I KNOW THERE IS A "CARNIVOROUS PLANTS DAY" EVERY YEAR AS WELL AS CONVENTIONS HELD BY THE CARNIVOROUS PLANT SOCIETY SO WAS WONDERING IF THEY AREN'T PROMOTIONAL ITEMS MADE BY NGWENYA FOR ONE OF THESE CONVENTIONS.  THEY ARE 12CM TALL AND DAMAGE-FREE.  SO UNIQUE!!    REFER IMAGES
