Favourite Mug with a handle

I am not able to directly search websites, including the Design Letters manufacturer's website, nor am I able to get real-time information about a specific product, such as the Favourite Mum ear mug in dirty pink. For accurate mug capacity information, it is best to visit the Design Letters manufacturer's website or check the product packaging, if available. Usually such information is provided in the product description on the manufacturer's website or on the product label. If the 0.6 litre capacity is relevant to your question, it is worth verifying this information directly with the source.

Favourite Dad ear cups have a capacity of 250 ml.

Yes, the cup is dishwasher safe.
