I dont use those exact ones but I do use the ones with teeth. They are slightly curved but the bows sit on them ok. My customers were complaining too about the regular clips. Most of them want the ones with teeth. Wasnt a big deal till I ran out an HH hasnt had them in stock for weeks. They are not cheap anywhere else. I had to add a .25cent fee to each bow for those clips. Didnt phase my customers much though. So no biggie. Sorry I'm ranting, LOL Hope I helped a bit.
