Sensei 67mm Filter Stack Caps

Being a simple mechanical device, this item either works or it doesn't. Machining is correct with respect to threads, so mechanical performance is as expected. The useful measure of device quality will be how well it wears over time, so won't know that for awhile.

This is NOT a flimsy filter cap. This is a high quality and is very sturdy filter cap. Two reasons I gave it 4 stars instead of 5:1. It is made of Aluminum and can stick if you screw the filter too tight, just keep it a little loose and you should be OK.2. Before using, you must use soap and a soft toothbrush to wash them since there is a little oil on the threads that can smeared the filters accidentally.

What a wonderful way to keep filters organized in a compact package easy to bring on the go!
