ミニ4コーナークランプ（1/2インチ×1/2インチ～5インチ×5インチ対応）

Putting together a small model frame was much quicker with these since they hold all four corners at once. The 5-inch max capacity was just right for my project, and the clamping felt solid and secure the whole time.

The adjustability range is the real win here—I went from gluing tiny model frames to a 5-inch shadow box without switching tools. Everything squared up perfectly with zero slippage while the glue dried. Definitely worth the space they take up in my drawer.

I've been using these corner clamps to build small shadow boxes and they hold the joints perfectly square. The quick-adjust mechanism really speeds things up when switching between a 2-inch frame and a 4-inch one.
