Addiction by Ayako is a Japanese brand I like. I get them off Ichibankao. I've played with the eyeshadows some. I have Cafe Mambo form the Spring 2014 Collection, and Pathos form the new Fall 2014 Collection, as well as Beige, Earth Wind & Singita. Addiction eyeshadows can be removed easily from their case(the glue is not very heavy, poke a pin through the hole it comes right out no heat) and placed into a separate case. They have 2 different sizes of palettes.
The small regular single cases are shiny black. The palettes have a clear red inlay on the black plastic. They are very shiny.
Top to Bottom: Beige, Earth Wind, Pathos, Singita, Cafe Mambo.
So far Addiction seems to make good shadows. It's just tough to buy them because of availability, price mark up and lack of swatches in the US. The palette system they have is just like Surratt. I use double sided tape to hold them in place. The Addiction eyeshadows have a tiny bit of glue on them that holds them into the small cases they come in. You push them out through the hole on the back. The glue stretches and is not hard like a MAC shadow. It's not enough glue to really hold it into place in the palette but you could try. It's a system that like Surratt doesn't make the shadows fell the most stable in their palette, some kind of magnetic or snap in system would be better.
Update 2024: Addiction is now sold in the US HERE.
I agree it falls out not the best modular system . What do you recommended for the best modular powder system you've seen?
