The mail just came and........

I got my Save The Date Magnets!!!!!! They are perfect BUT.....the envelopes are the see through vellum ones?????
Can I mail them in that? It seems like it will be hard to write on??? Maybe I should go to AC Moore and get different ones???

congrats ... not sure about the envelopes, try addressing one and see how it comes out. if you dont like how it looks buy others or see if you can exchange with the company you boought them from
