I have to use business cards....
I purchased this comb attachment after hearing about the durability of it. I am normally dealing with hair that is extremely curly and I was looking for an attachment that would last me some time. I have a RUSK blowdryer that has a matte texture. The rings that came with this attachment weren't working for me so I ended up having to use business cards to hold the attachment onto my blowdryer. That is the downisde of this attachment for me. Other than that the comb works great and my hope is that the business cards stay put so the comb stays on my blowdryer!
