Marcos paper
www.marcopaper.com and papercreations.com both carry the cubes for about $ 3.25-$3.50 plus no tax unless you live the state where these stores are. Turn around time is about 3 business days. That is quite a bit less than we can get them through SU even with demo discount! I had to look elsewhere since SU has been so behind in shipping. I made a bunch of these with matching RSVP pen and put in large gusset cello bag tied with ribbon. Make great gifts for teachers, etc. and I have sold lots of them in craft fairs.
