Amazon saves the day!!!!! Again.....
Size: 4 Pack, Color: A-Ivory White
These adapters are AMAZING!!! I live in an old home and all the wall plugs are two prong. But it seems these days everything is three prong. I had no idea until I saw these on Amazon, three prong adapters even existed!!! Amazon, once again, you've saved me lots of frustration and made my life so much easier. Thank you!!!! Very sturdy. Well made. Excellent price for 4!!!!!
