TURQUOISE 20th Anniversary is a commemorative doujinshi, marking Nadeara Bukichi's two decades in the business along with a glossy new collection of Nadia Secret of Blue Water illustrations. And pretty much every illustration features Nadia in Nadeara Bukichi's signature stick-on panty, so it's quite heavy on the fan service.
Harinpikku 2010 (ハリンピック2010) which by the sound of that title and the sports theme of the images, I'm assuming to be a play on the word 'olympic.' But it could mean anything! The collection features anime girls you should recognize from shows like K-On!, HeartCatch PreCure!, Darker than Black and a few others, all wearing the undergarment that Nadeara Bukichi is famous for.
