Brass core chips? (2 Viewers)

[Fishman]

I came across a local listing of Nevada Club brass core from Spinetti's. Listing says 15gram chips.

It's not my listing.

I haven't seen this in my research yet.
Wondering what these types of brass core chips are about?

Those have been around for years. I can't imagine them stacking very well.
