I just got a bunch of metal butterfly clips (with sparkly butterflies on them) and have been trying them on my girls today. My puppy has thick hair and the adult has very thin hair on her head. I was surprised at how well they stayed in (all day!). And if they did slip a little it was very easy to adjust, not a major ordeal like using the bands. I really like them much more than I thought I would. I thought they were pretty, but probably impractical until I tried them. I will be using them most of the time now instead of bands, even for every day around the home (unless I have a special bow that matches an outfit). They don't break the hair when you take them out. I had tried the plastic ones for babies previoiusly, but they fell out really easy. These are not like that.
Anyway, sorry to go on, I was just so surprised. I bought them to sell but will probably sell less than originally planned now because I have found out how great they are so I will be keeping most of them for me. If you have a boy I guess you could take the sparkles off and just use the metal clip or maybe glue something else on in place of the butterflies. Here's the link -
