I SOLEMNLY SWEAR THAT I AM UP TO NO GOOD™ LARGE COFFEE MUG
Planning to sneak into Hogsmeade for a butterbeer? Having a midnight duel in the trophy room with Draco Malfoy? Maybe you promised Hagrid you'd feed Fang or teach Grawp some English while he's away. If you plan to sneak out of Hogwarts castle then you'll need to use the Marauder's Map and mutter the words ' I SOLEMNLY SWEAR THAT I AM UP TO NO GOOD™' to activate the spell and bring the map to life! Mischief managed with this fun design of the famous children's book quote from the world of Harry Potter.

I was looking for a cheerful, vibrantly coloured, fun, extra large , MCM designed mug for my first coffee of the day. This fits the bill! The print is purrfect and the colours are SO vibrant. The design definitely gives a true MCM vibe. The placement of the art is the only negative for me. I would prefer the main image be on opposite sides of the mug, rather than placed so close together, and not able to be seen by the drinker (me!) or the person opposite me (if there is one :-).

I am super happy with this mug! It is exactly the size I was looking for. The image quality is good and I find the handle really comfortable.
I was absolutely shocked by how quickly my order arrived! I placed my order on a Sunday and it arrived on Wednesday, and I live in a very rural area. Super impressed! Thank you for a great experience!

I ordered this great mug as a birthday gift for a few friends during the pandemic, since I could not physically meet up with them to wish them personally. The mug arrived in great time, and all my friends love it! The print turned out great!
