A Tip For Storing Some Glassine Envelopes

I'm not a frequent visitor to Wendy's Hamburgers, but since one of their restaurants recently opened in my community, I purchased a couple of single burgers which are wrapped and served in a open half size box.

I've found that the cardboard box can be re-used (assuming they are clean) for stamps as they just about perfectly fits a #3 glassine envelope and you can fit about 50 or more glassine envelopes in each half size box.

I find it useful for sorting and/or separating stamps and since they come free with every burger, you can't beat the price.

Nothing very exciting, but just a tip that some collectors may find useful.
