If you're looking for something to sit on a shelf or you like to drink your tea or coffee it small quantities this is the product for you. While I think it's a very cute idea (I'm not a morning person so appeals in that regard) and the lack of handle goes mostly unnoticed due to the outside of the mug remaining cool due to its sloping interior, in reality there is very little room left for contents. Moreover, the top of the mug does still get hot, so make sure you're always reaching for the bottom of it.
Overall, this mug would make a lovely little novelty gift. But don't buy the set if you're looking for more than a few mouthfuls with every cup.
