Printed on washi material translucent sticker paper. Stickers won't be able to cover up existing writing or prints on planners. These were designed specifically for undated common planners.
Loveeeee these stickers! Had to knock it down a star because my batch of stickers, the first half of the stickers are not aligned properly. Despite it going against my perfectionism, I couldn’t let the slightly misaligned stickers go to waste! I figured it was just the couple I got.
