Plastic borders make the sturdy sandbox that you've been looking for. You can put them anywhere and move them easily. And the borders fit together snugly, so the only sand you'll lose is the sand that kids put in their pockets!
 
Plastic playground borders are smooth and have no splinters, unlike wood. They look great. Anyone can install them, with just a solid hammer or a mallet. And if you have to relocate
the sandbox, the
plastic borders are easy to move and reinstall.
