The Stanley Stacking Beer Pint 0.47 L in Matte Black Pebble is a lidless vacuum insulated pint glass that stacks into another one for storage. It is a glass replacement for camp and garden rather than a flask, so the insulation is there to keep a cold drink cold for a session, not all day.

• Stacks infinitely: the tapered straight walled shape lets empty pints nest into each other, so a set takes up almost no space in a box.
• No lid by design: this is an open pint glass, so it makes no leakproof claim and should not be packed full.
• Will not break or shatter: 18/8 stainless steel instead of glass, which is the point of it outdoors.
• 4 hours cold, 15 hours iced: enough insulation to keep a drink cold through an evening.
• 200 g and dishwasher safe: BPA free throughout.
• 4 hours cold
• 15 hours iced
