Ecotots Surfboard Growth Chart: This is our Ecotots Surfboard Growth Chart. It’s made to hang on the wall with a keyhole lock in two positions, so you hang it this way, uses the surf board these stripes are left natural so you can mark on it but also you can hang it this way & use it as an extra hook. What’s great about it is that kids instinctually love the surface to put stickers on. So it’s a great way to put, to collect stickers without putting them on doors & ceilings & everything else.
