Pros : Tips are tiny tiny and got mix super super super hard over and over again to get mix going. If you don't, water will get out & it makes a mess. Make a template of clear on clear so you can see how they look thin, thick, chunky, water, full, etc... Sometimes difficult to find consistency in more ways than one! Also Pain that you only have 3 tips so if you want to bounce between colors and only want to use small tip you gotta keep cleaning it out and that is a pain in the biscuits!!!
Cons : See above. I have to admit very disappointed on this product.
Other Thoughts : Look for other options for this effect/detail.
