Lolita23q x Aqua Silver

Lolita are going to make a collaboration with the jewelry brand "Aqua Silver". It will be a necklace, available in four different colors:
Silver, gold, pink and blue.
The design was made by the members (Soshi and Ban collaborate the most I think):

The silver one and the gold one will cost about 10.500Y (100€) and the pink and the blue will cost 11.550Y (110€).
It's selling separately.
In one side the design is all the band members, and in the other, the logo of the band.
Soshi uploaded a picture of the necklace a few days ago:

You can't buy it overseas, so you must be in Japan for purchase it.

I think it's kinda expensive for only a necklace >< ~
