Good quality, thickness and size to seal vents, along with caulk to seal the gaps. Would be better if one side was painted black, so they wouldn't be seen thru a screen vent cover. Do not use a solvent based paint spray to paint them as the solvent will dissolve the foam.
Excellent!! Arrived safely and without damage. Ninja supply is great!! Will definitely order from them again.
A little too expensive.
