I just bought a set of primary-colored Pyrex mixing bowls, from the 60s, I think, for $5. And another medium bowl in a pattern I didn't have. And another large yellow mixing bowl. I bought the primary-colored set (and the pink set, which was $8) with the intention of selling them, but now I'm hesitating on that. I never enjoyed selling on Ebay, and shipping breakables just seems so fraught...but we're moving soon and I don't want to pack up this sky-high stack of Pyrex!
