I have acrylic stamps and I have been trying to figure out what I have been doing wrong because I can never get a crisp image. I finally realized that I was using the wrong ink (distress inks and martha stewart brush tip pens) because they are dye/water based. So I purchased my first pigment inks and got a crisp image! I especially love the white -- it gives you a light pretty image.
I love these little inks. They have so much more ink that similar "little inks". What I love is that they cover the stamps perfectly and completely with the most beautiful ink! I can't wait to emboss with them. I used them when I made my own papers recently and the colors are so rich and warm. I plan on getting more of the sets in the future!
