I use these envelopes all the time since I send out and make my own greeting cards and invitations. I am always hosting bridal and baby showers. The quantity and price is a good value.
I am a card maker and send many many cards overseas to the troops so I also need to send the envelopes so they can send them back to their loved ones. I got a better value getting the box of 250 invitation envelopes vs. the smaller 100 size box. Love the value!
