Use this "Income Tax Return" window envelope with a Peel and Close flap to easily mail or deliver any tax return. A blue interior tint adds security while the cellophane window allows the taxpayer name and address to clearly show through using a slip sheet. Add a professional touch by imprinting your return address on the back flap. This 9 1/2" x 11 1/2" envelope is constructed of 28lb paper.
