very hard mostly unusable stampers [SEP] i recently purchased a bunch of stampers to test these included these were among the worst i tested all of these are hard stampers with no squish to them the green is the hardest followed by white then the red the one i received was actually pink when they are this hard know that you need to roll the design on rather than press it on rolling if not done carefully can lead to smudging also hard stampers are not forgiving on curved nails it will hit the highest part of your nail and miss the lower areas i also found that the hard stampers do a bad job at filling in solid areas of designs but only work well on designs with fine lines the red pink one was the best of this bunch very similar to the konad double ended stamper although i prefer the konad because it is slightly larger i made a full review of the stampers i tested here nailstampingaddictwordpresscom nail stamper trials
