Slide Mounts for 6x7 format slide photos - gepe , hama, matin

[sanjayc]

Hi, I am looking for slide mounts - preferrably glassless for 6x7 format - 54mm * 68 mm . I came across gepe and used them. Stock seems limited . I stumbled across hama and matin brands on the net. These are all plastic mounts, with gepe having metal masks in between.

I was wondering if gepe mounts are available in singapore and if anyone here has experience with hama or matin or any other brands?

thanks in advance.
