I would give these brushes a 10 if I could. I bought them on sale! So for the sale price Big Bonus! Either set will do the job for The painting of most stamps. I was quite surprised at the performance of the Detail set. Easy to stay in the lines of a stamp. I stamped several very small images & these brushes kept their point, applied paint exactly in the areas I wanted. Even the regular brushes which are larger have such a perfect point you could still paint These tiny images. The sizing # of the regular brushes would equate to a size 4,6,8,& 10 or maybe 6,8,10 & 12 & then the 1/2 inch flat. Altenew uses Number size of 0,1,2,3. Very happy with performance of small images. I haven't tried them for large images or backgrounds yet. But love having the control. I hope my photo will do these brushes justice. Having them come in a brush holder case was a Bonus!
