OpTech 折疊收納袋 303 (3''x3'')

I was pleasantly surprised by how sturdy this little pouch feels for its size—the fold-over closure keeps my adapter securely in place without any fuss. It's lightweight enough to toss in any bag and barely notice it's there.

Didn't expect much from a 3x3 pouch but the fold-over top actually keeps my little 50mm snug without any padding bulk. It clips onto my belt loop and I forget it's even there until I need the lens.

The fold-over flap keeps my 50mm adapter snug without any velcro sticking to my fingers. Only gripe is there's no belt loop, so it just floats loose in my camera bag. Still, the padding is surprisingly thick for something this small.
