Gibson Strap Button Aluminium

Just like any other Gibson product I've had, this is a very high quality part. However, I don't understand why it costs twice as much as some other alternatives that I've seen. Surely, for people who need a retrofit for one of the vintage Gibsons in their collection, this may be the most period-correct part on the market (after all, it is made by the same company that made the originals), but for the more sensible musicians who just need a quality replacement, there are plenty of cheaper alternatives that aren't in any way inferior to this product. I think its high price is unjustified.
