These are a great invention my son loved his and at this price even better.
4 water colour markers
colour eraser and wipe cloth
built in storage
can be used on floor or hung on wall
Just doodle, then use the colour eraser and start over again.
I loved this and aquadoodle mats as no mess
Still quite a bit of stock dotted about within 75 mile radius of Birmingham. Hope this helps someone.
