Traditionally a Hiball glass is taller than an 'Old Fashioned' and both taller and wider than a 'Collins' glass and whilst a number of the other Utopia glass ranges have Hiball glasses within them, this is a range of just Hiballs. Tall and straight, some with heavier bottoms some with lighter some nucleated with 'Activator Max' some without and some are made from toughened glass but they all have one thing in common - they are beautiful glasses. This glass is stamped but there Is an unstamped glass available so please make sure you have selected the item you require.
