You can use the same Leuchtturm / Lighthouse album with as mentioned above 2C or 1C sheets. They are non PVC sheets. I use the Grande 2C sheets which are A4 in size, lighthouse uses European holes so fits 2,4 and i guess 6 ring binders. Normal PMG graded notes fit perfectly. Use the 1C - for the larger ones. I just bought the new lighthouse PUR grande albums - they are really nice. One recommendation I was told - was to stand them upright, not flat down, by a very experienced collector.
