I am really happy with these earrings! I have terribly sensitive ears, and these have been worn continuously for almost 2 weeks without any irritation at all. I will absolutely be investing in more pairs of Blomdahl studs as 'every day' or 'rest' pairs.
My only two pieces of feedback would be to do this style in more colours, and to have a comparison picture of the two sizes - it took me months to figure out that the 5mm would work for me better than the 8mm.
