This is a second press of the band's [freely-distributed debut single][1], after that press completely “sold out” on the first day. This second press is identical to the first, except that it was sold (rather than being freely-distributed), had a slightly lower pressing limitation (1,500 copies vs the original's 5,000), and included a CD-case-sized sticker.

I've differentiated the UPC for database purposes by adding a “(B),” but please note that the UPC is probably the same as the first press (though I don't own a copy and can't confirm either way).
