Have been using them at work for five years so bought them for home. Carrier sheets are great for small or fragile documents that can be damaged if they are fed through the scanner without a carrier sheet. If the document is flimsy, has torn corners or edges, is very valuable and damage is not an option, or the document is too small, envelopes are great! Just insert the object and run it through the scanner. Note that small items can be output digitally in full page size if scanned into an envelope, or at least in one of the programs I use. Software applications may have settings to digitally display at original size or resize after scanning - or other software applications may behave differently, but I haven't looked into that. For my purposes it didn't really matter. Only say if it matters to someone else.
