1980s style flip-up 6x4 photo albums in a box of 3, each album holding 100 photo

I am looking to buy sets of photo albums to match the ones I already have [see photos). They are in the 1980s/1990s style flip-up, held in a box with 3 photo albums in each box, each album holding 100 6x4 photos. One box has 3 black photo albums in and the other has 3 red photo albums in. Each box is 305mm x 170mm x 115mm. Each photo album is 300mm x 165m x 35mm. If possible I would like to buy 2 boxes of red photo albums and 2 boxes of black photo albums. The boxes were originally bought from WH Smith.
