With these ink pads, you'll be able to stamp images with precision and detail like never before. These pads are made of water-based ink, so they sag over time as well as providing a brighter, richer finished look. Plus, you will be able to combine them with a variety of colouring options without worrying that the stamped image will smudge. Each colour is stored in an individual plastic box, so you can easily find the right shade for your project. They can be stacked up one by one, which makes it easy to use and store. And when you're done, these ink pads clean off skin easily. This will enable children to use their imagination, creating a great finger painting on paper, fabric, wood, plastic, etc., but they also work extremely well with darker materials like cardstock or paper.
