KISS Gel Fantasy Nails Short Length KGN12, Pink, 28 Pieces

Does the package contain the glue and tabs or are these items purchased separately?

After application, my cuticle/nail edge is reddish purple, like in some of the reviewer’s photos. Does anyone know what this is or how to fix?

Are these reusable? Or do you throw them away after one use?

Can I use reegullar polish over the top of these nails? How easily are they removed??
