I'm gradually building my collection of these handy little stamp pads (ten colours and counting). I use lettering stamps in my bullet journal spreads every week and I like to co-ordinate them with the stickers and washi tape I have chosen for that theme. So these stamp pads are perfect. They are affordable, with a good colour range, and small enough that a growing collection doesn't take up too much space (and they are stackable and have little stand-up feet so you can store them a number of ways). The shape is also helpful - the point allows them to be used to fill stencils or even for precision-inking different parts of a stamp in multiple colours. I love them so much I'm about to order several more :)
