The Bloom mug may be made of melamine, but this shouldn't stop you from also using it inside. Its stylish appearance has been inspired by sanded down pebbles. This mug has a unique speckled and matt finish. Naturally, the mugs are BPA- free, lightweight, extremely strong and stackable. Perfect for an intimate rooftop dinner, a sizzling summer barbeque or just at your camping table. And if you cannot wait for lovely weather, then why not use the mug inside! The Bloom mugs are, like the rest of the Bloom dinnerware collection, available in four colours and great to mix and match together.
