This polish has been sitting at the bottom of my to-swatch bin for ages now, so I'm finally showing it to you today. This is Temptation from the OPI Designer Series. Temptation was released in Fall 2011 and although it's not the holographic type of DS that we all love, it's still really awesome.
Temptation is a sheer blue-purple base with a very dense mix of blue, purple and pink glitters. The dominant glitters are blue and purple, but there is definitely some pink in there as well.
This is a versatile polish because it can be worn alone with three coats, which is what I've shown you here, but it also starts out sheer enough that it could be layered over another polish. The formula was easy to work with and it didn't feel thick like a lot of these type of glitter bombs do, even after the three coats plus top coat.
Correct me if I'm wrong, but I believe that DS Temptation is now available as part of the core OPI DS line.
