So here's how we did it. - very simple DIY.
As it's for our baby Jules, we need to sand down all the rough and sharp edges in picture 2.
After sanding, brush off all the dust with a small broom and we can start to varnish the crate!
Next, apply 2 coats of varnish. I've used the IKEA "antique glazing" for this worn down look.
See! in Picture 6, you can see 2 stow away screws at the bottom of my magnetic tray which tried to "roll" away but couldn't!!! hahaha
here's the finished product!
here's the IKEA varnish which i used for the wine crate.
