Japanese artist Mizutama is known for her kawaii and whimsical illustrations. She started making eraser stamps since 2005, and has been holding workshops all around Japan. Since 2012 you can also find her illustrations on other stationery items. I thought it might be helpful to make an overview of shops that ship Mizutama items worldwide.
At CDJapan (JP) you can find several Mizutama books including this e-Mook. The mook contains 30 pages about how to make a cute notebook, but the most important part are the included rubber stamps by Mizutama.
Cute Things from Japan (JP) offers a nice selection of Mizutama stationery, such as these cute clear stamps. It’s a fun set that allows you to stamp the hair and clothes of the girls in different colours.
Being a fan of Mizutama, Kaila from Rainbowholic (JP) sells a couple of her items, such as this Kawaii Illustration Lessons Book.
Recently Mizutama has been posting Instagram videos of how she illustrates coasters, which is very soothing to watch.
