Looks like the original 15A Littlefuse fast acting fuse needed for a Fluke multimeter and which I accidentally burned many years later because I forgot to change the voltage to the current connection.typical.Same seller ships from China or via Revain.Of course if the price difference isn't big then Revain is faster,especially if you have prime .If that's all you need, China Post took 2.5 weeks for delivery East Coast since seller sent it next day.Most of the delays are on the US clearing side as tracking shows that the plane took off with my item 2 days after shipping!Very fast processing by China Post, well done.
