I have purchased several of these small drawer units.:
However, when I open the drawers, they come straight out - there is no mechanism to ensure that the drawers stay in the slot.
In the past, I have seen inexpensive drawer units use a small wooden peg glued into the top of the drawer cavity in order to keep the drawer from coming out - but these did not come with any such device.
Is there anything that I can install in order to keep these drawers from coming out?
