Looking for a tooth mug with a false bottom, I came across this model. The compass in the ground is, of course, a real joke - otherwise the double bottom does the job but only partly because it is relatively easy and thus contributes hardly contributes to stability of the cup. Overall, the cup with a total height of 9 cm (about 7.5 cm Clear height) less than expected. The rim of the cup is not processed very valuable, but the outside slightly sharp.
I must confess that I would have expected more for the price and the brand name HABA - pity.
