It is VERY hard to find glass spray bottles, and hard to find good spray bottles in general. I absolutely love my high-quality Grove Collaborative (affiliate link) one, and can't wait to get a few more. I use this one for ironing, but also want one for homemade cleaning products and such. They're just too handy, beautiful, and lasting.
