On the surface this looks like a good ink pad.
But the lie has been hidden to bring it in for max profit.
The individual pads are quite thin , and under half the over all depth of the stamp pad as a whole.
The individual pads are made from a foam that I feel is not the best suited for absorbing and transferring ink onto the stamp so as a result there seems to be a lack of ink , which is actually not the case as when a finger is pushed against the pad , there is an evident ink.
Another problem with this type of "all colours in one " is after a while , with out a strict cleaning regime (after each colour use ) each colour pad becomes cross infected with the other colours and the weak colours yellow etc start to loose the battle to live ...slowly becoming green ..then blue ...then black mud gunk colour ...all eventually follow suit .
My advice would be to buy individual ink pads with each colour .
