Hi Yuri,
check this out: http://kuertengmbh.de/de/Reparaturteile/Klammern-Naegel-Platten
You can skip on the right top corner of the webpage to english, if you don´t speak german ;-).
Unfortunately they don´t have some of them in stock right now, but i am sure if you check everyones in a while, you will be lucky.
Hope that helps!
Greetings
PS: I love your Boots! Keep up the great work.
This is exactly what the world needs! Not those cheap, plastic shoe´s from far east.
