Ocean San Marino Rock Glass, 245ml, Set of 6 (1B00409)

Our review

This is a six-piece set of Ocean San Marino rock glasses, each holding 245ml. The wide, straight-sided tumbler shape is the classic choice for whisky on the rocks, but it works just as well for water, cocktails and other iced drinks, so one set can cover most of what a home bar or dining table needs. The clear glass keeps the focus on whatever you pour, which matters if you serve drinks where colour and ice are part of the appeal.
They suit households that want a matching set rather than odd glasses, and small bars, restaurants or hotels replacing tumblers in bulk. Before buying, think about the 245ml capacity against how you actually drink: it is a moderate pour, fine for spirits with ice or a modest cocktail, but anyone who likes a long mixed drink may prefer something larger. Also check the height and diameter against your cupboard and dishwasher space, since rock glasses are wider than highball types.
Compared with similar tumblers, the main things to weigh are glass thickness and weight in the hand, whether the base feels stable when set down, and how the rim is finished. Those details affect how long a set survives everyday use. If you want thin, delicate glassware this may not be it; if you want a plain, versatile tumbler set, it is a sensible option. Available on Sokonia.
