I bought it after seeing Silk miniatures ad on TV as Im living in a remote area so it is quite not possible to get in local stores.
By the way, there are many silk chocolates available and you can buy those in loose but I bet you cant find these chocolates in loose because these are premium chocolates and it must be used in special occasion only. I am a big fan of dairy milk chocolates and their silk collections. One of my favorite is Silk Oreo until I got these miniatures. The packaging of this silk collection is really good compared to Cadbury celebration. The golden colored lines on the border of it give a premium look. No matter why they do call it premium miniatures.
These miniatures are just like ice cream but in the chocolate version. I have never tasted sea salt chocolates but glad I tried it and its good but among these four types of it I liked the Butterscotch Silk chocolate the most. The price is quite high by the way and may have to think twice while buying compared to other dairy milk chocolates but you wont regret after buying it.
