A standard single shell fits very well purely into this framework; She has light but not too much play - this is again, great. However, for the specified double-hull this rather cheap plastic things are not really suitable, because the back of the LP is simply too wide. You can catch a lot of feeling when you back at a slight angle pushes / pulls, by pulling them from above. However, I would not recommend this procedure if you want to take out the record more than just once a year. Also I doubt that these plastic strips survive a frequent removal undamaged.
One can not expect wonders of the world at a price of just under 4 per frame, it should be clear in advance, but that does not really fit despite specially mention the double hull spoils the fun of the beautiful view on the wall a bit. Who has a lot of double-hull and this will take on a regular basis, should rather stay away from!
Covered only two stars that I forgive, but I can live with the defect will personally (rare extraction) and probably again get a pack, I forgive three star.
