90 Degree Positioning Squares, Clamping Square, Right Angle Clamp Corner Clamp Woodworking Tools for Wood Cabinets, Carpenter Tool for Photo Frames Box Drawer, Set of 12（3" 4" 6")

Not precisely square but pretty close. A piece of blue tape on the larger ones & i have a perfect 90 degrees.

This is my third style of corner clamps. I think they are great, especially for the price. Each different style has their own purposes and these are very helpful. The different sizes have a wide range of applications.

These corner clamps are very solid, manufactured from rigid plastic. They seem accurate and as a 12 piece pack are great value

Nice and strong,well made and good variety of sizes. I see some reviews from people saying they are not a perfect 90 degrees. The ones I received are fine. For the price they are more than accurate.
