There is something you should now when buying luxury comforter sets for your bedroom or as gift for your beloved.
Before you purchase a silk duvet with a silk casing you should ask what the momme of the silk casing is. Momme is the unit used to grade the quality of silk. A silk casing should have at least a momme rating of 19. Anything lower and you would encounter durability issues and herein causes the issue. What would initially seem a great price for a silk cased duvet could soon turn into something worthless with a hole in it. We are not saying do not buy silk cased silk duvets, but just be sure you know what you are getting before you make a purchase.
If you are afraid of the hassles of a damaged silk cased and silk filled comforter, then you have better consider cotton cased one.
