Review on Clear Squeeze Bottles with Excellent Credentials by Josh Elkins

I bought these squeeze bottles for applying epoxy for fiberglass repair. All 3 bottles are not air or liquid tight. I tightened each cap of each bottle and found an air leak between the bottle and the cap. I've even swapped the top pieces to no avail. I filled it with water and noticed water leaking from the screw cap and bottle hinge when I squeezed it with minimal pressure. How can you screw up something so simple in a squeeze bottle? I would return them, but the expense doesn't guarantee a payback. Into the trash. Lesson learned. Buyer Warning.
