Wow! I'm really surprised that the delta marker to the Copic so much same. The Copic markers are much more expensive, but I really do not see any major differences. No stripes or the like. The inks dry quickly and there is very beautiful, bright colors. The only thing I miss is the beautiful brush tip from Copic, unfortunately they are not refillable, but because they are so beautiful cheap, it makes me to buy anything from other markers! There are not as many colors as other markers, but I find the amount of 80 pieces actually enough. The pen fits comfortably in the hand and does not roll so fast thanks to its form from the table)
I am very satisfied and will continue to work with the delta markers!
