Review (1/5): Very small
Update: gave these a try despite their size. Cannot recommend. Makes a really uneven, lopsided bun because the middle is much thicker than the ends that snap together. So the result is a very uneven bun.
And this is definitely NOT for long hair. I use the medium size one on my toddler, so I couldn't picture using one even smaller! Unless the intention is for your hair half-up/half-down with just a little bun?
