Looking for the quintessential Schiit schwag? Look no further. Here’s a set of four PC board coasters, perfect for resting your drink on. Well, at least if you don’t mind maybe still ruining the nice wood finish underneath the coaster, because these things have holes in them.

Yes, that’s right—these coasters are made out of PC board material. And yes, that’s right, they have a PC board pattern etched on them. It’s even plated in gold (technically, Electroless Nickel Immersion Gold, or ENIG.)

Aaaannnddd…you can build these coasters into a working hybrid headphone amp if you’re a super-mega-geek like us. The docs are available at schiit.com/coaster. Have fun!
