These were the three I chose, called Nocturne, which is Black, Fallen Leaves, which looked like a Dark Brown, but more on that later, and Twilight, which was a Dark Blue.
The pads are slightly smaller, and with a completely removable lid, not the hinged type.
The full range is 24 colours, which is a lot more than are currently available in the original range.
To return quickly to the lid, it fits over the pad, leaving a gap between the top & bottom of the pad, which I do think means extra care will need to be taken to ensure they are closed properly, as you won't be able to tell just by looking at it.
Looking at the info on the back of the pad, it reads exactly the same on both.
" Pigment ink for Fine details"
'Longest lasting Pigment inkpad available.Perfect for using watercolours to colour stamped images'.
From that, it sounds as if there is no difference in the inks. One lady on SCS who phoned the manufacturer to ask about the difference was told the new one has a slightly longer drying time, but I didn't see any noticeable difference myself, but obviously cardstock can play a huge part in that aspect.
I used 2 Lavinia Stamps to test, the Witch for a solid image, and the window for one with some detail. I also reinked my Onyx Black to give a fairer comparison against a new inkpad.
Next onto the Fallen Leaves, which on the pad cover looks distinctly like a dark Brown.
But, as you can see, it doesn't look Dark Brown when stamped. It just looks like another Black to me. The image quality is just as good, it's just not the colour I expected from the lid.
Last one I chose was Twilight, a Dark Blue.
It is a dark Blue, and very similar to the lid colour.
When I opened it, the pad actually looked Purple, but that vanished on inking the stamp. Again, a good solid image, and all the detail of the window was picked up too.
The new & old pads side by side. You don't get the little fabric cover with the new ones. The pad itself seems to be the same construction as the original, nice and firm.
I found no difference in the ability to heat emboss with it, it works just as well as the original Onyx Black.
