you have several options -
first I might suggest browsing the links in sticky at the top of the forum of various stores to see if they might have something that works for you.
If you don't find something, I'd reccemend possibly creating something like that yoruself. There are several tutorials on how to make clip-ins but essentially you would need a small weft of hair, the clips and some sewing thread to make the clip-ins. Its a good option since you want something specific.  I also have recently started my own custom buisness, using synth, but if you're interested I could create something like that for a reasonable cost very quickly.

Damage is possible, however if you are careful and continue to properly care for your hair as well as  use the clip-ins properly, it shouldn't be a problem. For instance, don't sleep in them, and move the spot you clip them in at slightly to minimize how much the clips rub on your hair.

hope this helps!
