What's Included
- Teacher Quick Start Guide with sample lessons
- Four pages of premium double-sided stationery for every student - five different fun watercolor designs
- Two guided envelopes per student
- Fun sticker sheets for decorating letters (quantity scaled to class size)
- One decorative wax seal sticker for every student
- One bookmark for every student
- Sturdy, reusable, classroom-ready packaging - available in 3 colors
Mailing tip: Our wax seal stickers are thin and flexible, and letters sealed with them almost always mail just fine with a regular stamp. Once in a while, the post office may ask for a little extra postage for a sealed letter. If you want to be extra careful, add an extra stamp or ask for hand-canceling at the counter. Or just use them for journaling or hand-delivered letters!
