Comments about Adorama Adorama Filter Stack Caps 77mm:

77mm - the cap won't screw on the front of the filter (polarizer). Even these two pieces don't screw onto each other smoothly. You can actually hear the grinding noise as the threads travel over each other. [*].This is an ersatz product for something that could be a indeed practical accessory.

This solid metal lid and bottom allow me to carry all my high-quality and high-priced filters in a convenient stack, without risking a scratch to any of them. Huge space savings, to be sure.

Best protection for yours filters. You can save a lot of room in your bag. I mean A LOT! Just attach filters to each other and put this caps on both side. Use step-up adapter ring if you have different size filters. Finaly, You will have very small and very strong metall cartrige.

these stack caps are simple, easy and effective. They are very generic, and slightly different than pictured (the side with the female threads does not have the knoblike grip pictured on the website). The metal construction is durable and I've not had a problem with them at all. One should be careful when attaching a polarizing filter, as it can be difficult to remove the cap if you put it on too tight.

This product helps store filters efficiently. Regrettably, even when trying to thread filters loosely, they often stick together (even when not cross-threaded). That impairs the practicality of the product. On balance, space savings probably offsets this sometime hassle.

I love keeping filters together with the stack caps. They take less space than filter wallets. They are simple to use and simple to unscrew.
