Every time we wanted to protect our parquet before a chair went searching going on for a perfectly fitting felt gliders. And how is it in such moments, is never the matching point. Now everything is in a box and I have nothing more trim. For our domestic peace of the box was a good investment;) !!! I can not fault about the quality. To date (3 months) all gliders stick still good and the felt comes before me also quite stable and thick. Thumbs up!
