Hi all – Why do the sponge bottle products include an adhesive in the liquid? The stamps and envelopes already have adhesive gum that just needs to be moistened with water. Why add a second adhesive to the system?
Do you know if adding that adhesive has any implications for the preservation of the stamps and covers long-term? I'm new to philately and APS, and I've noticed that any time I receive mail from you people, it's plastered with lots of interesting stamps (adding up to the current postal monopoly rate). I assume y'all aren't licking all those stamps, so you use the bottles then?
Is there a standard practice of philatelic stamp moistening etiquette, say to use only distilled water and unicorn tears instead of the premixed adhesive bottles? It seems risky, from a conservation perspective, to add a second adhesive to the gum.
The main sponge bottle moistener brands I see on Amazon
are Quality Park and Klingy. Are there philatelic brands free of risky adhesives?
