The marker funtionieren, but not always ....

The bloke from Delta are varied, the bag is very practical and it can be good affairs.
The disadvantage is that it in the meantime the impression makes as if the pins have all the stickers on the caps hold not very long, but not too much bother, what I find, however, really not good that the advertised "Cool Gray" clearly a Warm Gray, and the textile bag for the bloke quickly tearing at the seams, when you can see over it they are really good bloke and suitable for use as in my case at school, you may only expect professional quality.
For my part I'm going over time anyway a set Copicmarker invest as they make themselves better.

best regards
