Small box with compartments for different wire sizes. I already tried one, and it melts evenly; the connections are almost perfectly bonded. The risk is when applying heat with a lighter (even though it doesn't require much time), so you have to be careful. Excellent product. It's only suitable for small wires. Perfect for automotive electricians. I'll buy it again because I prefer those few seconds with the lighter to the risk of a bad wire splice. I recommend it.

Love this product because it holds up to the standard that most suppliers cant even match, also does good job with little things when it’s important.
