the films are simply placed over the steel's, pulled down and the schwup wupp sits almost like a condom beautiful fold closely with barely room for air, Finally you subtract only the cover of the adhesive strips and the "cover"!
the films also make a stable impression, since the the steel's introduce relatively well forces on the sutures act would - but they keep well! clad steel of 70's is not a single film gone cracked / broken! think you can get out and do it again purely easily öffter.
the appearance of the steel's is in no way compromised, clear glass with original color reproduction. only the corners of the sheet are visible (are from) but I think this bothers non> see my customer image as you can see the slides good live!
Finally, I have to say for 10 just so bought and now I am vastly excited! should I have to buy from the beginning and already do! I can only recommend!
BEST PROTECTION FOR STEEL'S ESPECIALLY OPTICAL!
