Game Changer!
So much better than the applicators. Easier to get nice even application on RVs. Does much better getting around the awning poles and different covers.

opens bottles!
Size: One Size, Style: Bottle Opener
This bottle opener is very cool. It’s like a screwdriver, but it’s really a bottle opener! It has a grip to prevent your hand from flying off while opening a bottle. I also carry a bottle opener on my keychain and am always especially proud when someone needs a bottle opener and I have on right there on my keychain.

Great bottle opener
Size: One Size, Style: Bottle Opener
Love this bottle opener. Looks and feels just like the screwdriver. Easy to grip just like the hand tools. Good gift idea for the electrician or a diy person that appreciates quality tools.

Great bottle opener and looks cool too
Size: One Size, Style: Bottle Opener
Love this opener. Matches with all the other screwdrivers in my tool box and have it ready to whip open a beer whenever needed. Slips into the pocket to carry with you as well. Solid tool and I gave a couple buddies one as a gift. These will see many years of beer opening super fast.
