These cards love ALL writing instruments, including ballpoint, watercolor, fine tip gel pens, special inks, and pencil! They're 300gsm, and crafted from crisp white card stock from Europe. Ink soaks into the thick matte card fast to prevent bleeding and smudging. There are 36 cards, featuring 6 different designs with a beautiful glossy texture, so there's always the right one available at your fingertips for the right occasion. A festive canvas, for a meaningful greeting.
