Promaster 4002 モジュラーフラッシュシステム用フラッシュジェルキット（クリエイティブエフェクト）

The gels snap firmly onto the flash head without any adhesive, and the color saturation is surprisingly consistent across different power levels. I’ve been using them with a speedlight for portrait backgrounds, and the creative possibilities are instantly expanded.

These gels pop vibrant color onto my subject with zero guesswork — the holder clicks in securely so nothing shifts mid-shot. Works seamlessly stacked with my other modifiers too, which is exactly what I needed for creative portraits.

The included gel holder snaps onto my flash modifier securely, which made switching between colors during a shoot quick and hassle-free. I’ve already used the red and blue gels to create a moody portrait background effect—definitely adds versatility for creative lighting.
