Review on Ziploc Slider Storage Bags Quart by Veronica Goodwin

I received these to meet minimum USD amount to get free same day shipping on a cheap item I need right now; I use bags like this a lot, knew I would need more at some point, seemed like a wise purchase. Unfortunately for some reason several packages, at least in the first box, had defective sliders - they got lost the first or second time I moved them to close or open the package, rendering the packages virtually unusable. And re-gluing isn't easy, although I've managed to do it once or twice. I'm pretty sure I've used Ziplocs in the past (although I enjoy it a lot) and I don't recall having had this problem in the past. bad party? Possibly, but I'm not sure I'll buy them again in the future. . .
