These envelopes are made of durable yet pliable plastic and each feature a secure two button string tie closure. As these envelopes are a little smaller than the standard sheet of paper, 6.25 x 9.25 in (approximately 6 x 9 inches), they are perfect for smaller documents and checks. Don't let your smaller, yet valuable documents get lost in the messes of life. Keep them protected and in order with these bright envelopes!Details:Available in multiple colors6.25" x 9.25" each12 countButton and string tie closurePliable and durable plastic
