Welcome to the Forum.
It always helps to post a picture or two as it helps people understand what you are talking about.
Here it would appear to the casual observer that you have procured yourself a quantity of military spec gloves with the option of wearing "inserts" to one's mil spec gloves. But what sort of gloves are they? Are they of the surgeon's variety for performing an examination of a squaddie with a weird and wonderful ailment or rigger gloves for wearing while removing the tracks off a Abrams MBT? Who knows?
This forum has a place for individuals to buy, sell and trade their surplus items.
If you are unsure "test the market", in other words buy a few items to resell, to see if you can, before buying 1000.
If you've made a mistake don't spend too long crying over it, man up, learn from it and try to avoid making the same mistake again.
I am a collector, not a trader, I only buy an item if I like it and if I consider it reasonably priced. If I consider an item over priced, generally, I don't buy it.
