The envelopes we typically purchase are about the size of a check...these are a bit larger than a business card, so were much too small for our needs. It would be helpful to provide the dimensions in the product description.
These envelopes fills a need we have at our church to create our own offering envelopes without the high cost of having them done for us. They are a perfect size for checks and paper money + they are sealable. We just made up a template of our church logo and what funds we wanted to list then ran the envelopes through the copier. They turned out beautifully.
