Porte-Carte S Dragon

I have just recently gotten into the hobby and would like to enhance my experience. So ordered this..

I wanted to love this product because it is a great idea for what it is but the product came without instructions, no notice, there are similar pieces of different sizes. Went back on here to see if there's anything to download and ofc, NOTHING! 

I don't know about you but some guidance would have been nice, not everybody's an expert you know. Lo and behold, I tried putting it on on my own and broke a piece. What a surprise! Knowing that Philibert's selling something  fragile which comes without a notice is no less than disappointing! In short, not recommended for beginners  !
