This stackable mug features grooves for a comfortable, anti-slip grip and is suitable for hot and cold liquids. The virtually spill-proof valve in the lid prevents spillage, with only a small drop escaping before the vacuum seals the main flow. The mug has an angled spout for easy use and includes a 100ml and 200ml measure guide on the outside for recording liquid volumes. It is microwave and dishwasher safe and available in multiple colours. Optional extras include a handle for extra stability and a straw clip. Dimensions: 6.50cm x 15.00cm x 13.50cm. Weight: 0.07kg.
