This is a Brio Train wash way.
The two roll holders are stretched with a light rubber so that they open when passing through the train

What you need:
1x paint roller with inner diameter of 14mm
2x M4x40 screws incl. Nut and washer
2x M8 screw on the roll holders plus big washer

Have a lot of fun!
