I needed 6 X 9 white side closing invitation envelopes. Had to take these thinking what could a 1/4" difference make. PLENTY! Even though the invitation did fit inside all my printing was off and had to reset the template. Why couldn't I have 6X9? That's what your competitor has.
This envelope is the perfect size for handmade cards. I used a standard sheet of card stock and when folded in half they fit perfect in this easy to seal envelope. Will definitely keep these in my stock.
