A4 size unbleached kraft paper. There are two packs of 50 sheets each. I bought these but never used them. I probably haven't even opened them, but I'm listing them as used just in case. Thank you for your understanding. I hope someone who can use them will purchase them. ---- etranger di costarica PRNA4_A_01 etranger di costarica #etrangerdicostarica #etrangerdicostaricaPRNA4_A_01
