Sources Of Clear Stamp Envelopes

I collect worldwide. I'd like to sort stamps I want to mount by country, A to Z, in a long box about 4 1/2" wide. I could use glassines, but I'd like to see which country envelopes have stamps in them without looking in every envelope. I'm thinking clear (polystyrol?) flapless envelopes would be best, but I'm not sure who would sell those. Thanks for any ideas you have.

Here is a source that the American Philatelic Society recommended to its readers, since it no longer carries clear mounts.

I have placed one order with ClearBags, and the experience was a very positive one. If you visit their website, you may be overwhelmed by the number of choices. My order was for 5 different sized envelopes in single stamp to large cover format. This saved on postage.

If I remember correctly, you can order envelopes/bags without adhesive mounting strips.

Won't every envelope have stamps in them? I assume you will have one envelope for each country.
Maybe you want glassine envelopes. They come in a lot of sizes including some that will fit your box width.

Since you are likely using these over and over, you might consider top-loading cover sleeves. There are obviously various sizes available. The 5 mil thick ones are stiff enough to prevent accidental folding.

I'm using 5 mil SAFE ones for sorting, but there are other brands/choices available from the usual stamp/coin supply sites:

WorldWideWard

I use these:




Get them where baseball card supplies are sold. They are relatively cheap and can be reused.

Michaels, the crafts store, has clear envelopes which they claim to be archival. I use these to provide extra protection when mailing stamps in glassine envelopes. The range of sizes, however, is not as great as for glassines.
