NEW MAC Rose Lens 6 Shadow Palette

Just received this yesterday (Jan 14) and realized that I already have very similar colours. Cant return it. It's untouched and in it's box. Retails for $42 https://www.maccosmetics.ca/product/13835/115811/products/makeup/eyes/eye-palettes-kits/connect-in-colour-eye-shadow-palette-rose-lens?_gl=1*1f4r70e*_up*MQ..*_gs*MQ..&gclid=CjwKCAiAvaLLBhBFEiwAYCNTf3xVt5u-0TbDXHZByNRsYK5dy9zhu-EML2D7QYAsOwbEUrGZlxLSfxoC0NUQAvD_BwE&gclsrc=aw.ds&gbraid=0AAAAADSEZ0KqB8ki0QHittiSM48s-bcLl
