Thanks. The publisher is Kumon Publishing North America. It's a title for a series of workbooks for children and the books sell very well on Amazon. And I didn't find any customer reviews stating that the title is odd or something. I am very confused.I'd like to know where the book was produced. 'Stick' is a perfectly good verb. "Stick and Paste" is snappy, while 'sticker and paste' annoys me.
I hadn't heard of this particular series. Similar educational publishers employ local staff, not native speakers, for the local language version.
A sticker is something that can be stuck. To me, it's as strange as 'cutter and paste' would be.
