Batting Practice Equipment: Batting Seesaw

My child had trouble with weight transfer, so I bought this a year ago and it helped them improve. I'm selling it now that it's no longer needed.
It has been used only a few times, but there are minor scratches and scuffs in addition to what is shown in the photos. Please understand that this is a used item before purchasing. We do not accept cancellations after purchase, so please understand.
