Drawers
The drawers will likely be made of solid wood or medium-density fiberboard (MDF); have framed or flat slab fronts; and be held together with either dovetail, mortise-and-tenon, or butt joints.

Dovetail Mortise-and-tenon

Butt joint
Glue holds the parts together, though staples or brads are typically used to hold the joints together until the glue has cured. Dovetail joints provide the most strength.
