I didn't realize that Sally Hansen came out with a black and white glitter topper but I spotted it on clearance at my local drugstore and decided to pick it up out of curiosity. I've already had Hard Candy's Black Tie Optional for over a year but I've been looking for a back up for it... and I don't go to Walmart very often as it's out of the way for me. Plus the Hard Candy is a bit expensive considering the size... $4 for 7.8 ml so it's almost the same as paying $8 for a normal size (15 ml) bottle. I got the Sally Hansen on clearance for $2.50 for 11.8 ml so it is significantly cheaper than the Hard Candy especially on clearance.
In terms of application, I didn't have issues with either of these. Both have black and white hex and bar glitters. BTO has bigger glitters and more bar glitters. BTO is definitely much more dense than PP but I don't think that necessarily makes PP bad... it's just a different look. I think over a gradient I would prefer PP for a sparser look so more of the base can show through. On the other hand, if my base was just a creme, or if my application was lumpy and I wanted a cover up, I would reach for the BTO. I was impressed that I didn't have any clumping issues with BTO even though it is so dense. Oh and btw my base is Color Club Pure Energy... Sorry for the shrinkage at my tips! The base color was a day old when I decided to do this comparison.
You can see in the bottle that BTO is much denser than PP
Which glitter do you prefer? The denser BTO or the sparser PP? Any favorite black and white glitter toppers?
