EC5 connectors, including four set plastic cases and eight bullet connectors as shown in the product photo.
Only $2.48 per pair. This is the same product that sold more than $5 a pair by many other dealers.
Copper plugs are plated with 7u pure gold, not like cheap EC5 plugs processed with acid pickling to give a golden color.
The connectors use high quality plastic that is resistant to a higher temperature than those cheap mimics.
