5 laboratory flat-bottomed balloon vases

Set of 5 laboratory flat-bottomed balloon vases. 3 of 500ml, one of 1000, one of 2000ml. They are in excellent condition, neither cracked, not the slightest blow. I bought them, like many lab items, in an old hospital closing in rio de janeiro. I used them at our wedding to put flowers in them. A selection @nosmade.
