The Non-profit Direct-Mail #10 window envelope is used to mail your appeal letter. When you use a window envelope, the donor's name and address must be positioned so it will show through the window.
Non-window standard #10 envelopes are also available. These are addressed on the outside and then matched to the letter and response inside.
Envelopes print on the front and/or on the back flap.
These envelopes are meant to be ordered as part of a Non-profit direct mail appeal set, and do not ship separately. #10 envelopes that ship directly to you can be found under Business Envelopes.
The #10 window envelope size is 4.125x9.5. Crafted from a 24# white wove stock.
Large solids, photographs or screened areas are not recommended and bleeds are not allowed, because we print using pre-converted envelopes.
For complex designs which require printing then converting, please contact Castle Press for special pricing.
