Question about supplies

[camaro69]

I recently bought a few tea cards and when they arrived they were in a soft sleeve that on the
outside is the same size as the regular ones we use in our 9 pocket pages. But in the centre of these
soft sleeve is a place only big enough for a tea card, Just wondering if anyone knows where I can
buy some of these.Like a supplier. I had never seen these before. But I think they are such a great
idea for tea cards.Thanks.
