These are 3mm, square, purple studs (they also make them rectangular), and you get 50 of them for $4.73 USD.
I wanted to use a contrasting color with these, so I went with Zoya Pippa as a base.
The pros and cons of these studs: I can't find a single thing to complain about. They laid flat, were a great size, decent price, gorgeous. I was even able to cut them in half with a plain pair of scissors for anywhere I needed just half a stud on my thumb. These are great! I love them!
