Promaster 高階柔軟清潔布（附易開收納袋）

This cloth wipes my glasses and phone screen completely streak-free without any scratching. It’s also nice that the included pouch keeps it clean and handy in my bag.

The pouch is the part I didn’t know I needed—it stays shut in my camera bag, so I’m not digging crumbs off the cloth mid-shoot. It handles fingerprints on my viewfinder in one pass, and the fabric’s soft enough that I don’t worry about scratches.

Finally, a cloth that actually wipes off fingerprints without smearing. The storage pouch keeps it from getting dusty in my bag, which was my old cloth's biggest problem.
