Question: the sizes  how do i know if they will fit my album
Document: They advertised this as a trio of products meant to go together. But these pages fit neither album. This was false advertising.Do not buy!
5 pages, 10 sides. A bit pricey but are the same as the pages that come with the album, fit and look perfect.
The refills fit perfectly in the album - same size, same color, same everything. I loved the fact that they included extension posts, so I didn't have to buy them separately. I ordered two, and practically doubled the size of my album.
these albums and pages dont fit 2 4 x 6 pics next to each other completely unrealistic for 4x6 pics
I ordered 3-ring photo albums, which I love. This item pops up as recommended. It does not fit the albums I ordered. Why would you advertise these items together? Makes no sense. Of course I returned them.
I bought this refill pack for a photo album. Very happy with the quality and price. Nice addition to the album.
Here is the only realiable Refill for a PMV-206, and it is as the original that came with the album, so it a winner! Suggest you pick this item up if you want to add photos to your 206 album..
The additional sheets seemed to be what was expected, but  one of the extension posts was un-threaded and therefore unusable and as a result the sheets could not be added to my album. This is a don't buy.
Perfect as pictured. Shipped amazingly fast and packaged to prevent damage or bending. Purchased for standard three ring binder photo album and works great.
Timely Service & Fast Delivery. Aids in extending our family photo album to allow all items within one year of too many photos we've acquired. Now we're organized.
Answer: The PMV refills measure 11 1/2" X 11 1/2" and include metal extension posts for adding them to the Pioneer PMV-206 album. These refills are for use ONLY with the PMV-206 album and will not fit any other album.
