I had a little difficulty using them on my curved nails! I usually chop the vinyl borders off to make them sit nicely on my nails! But cuttin the border makes it difficult to keep the loose stripes in their places! I wish there could have been some other way to make them sit well on my curved nails! However, the vinyls themselves are of great quality! I apply them on a quick dry top coat! They did not peel off any base polish upon removal & also stuck to the nails nicely!
