Reusable cleaning glass spray bottles with silicone sleeves. This listing is for all 4 bottles with 4 sleeve colors (see photo) plus an extra yellow sleeve (not pictured). Bottles are used but will be cleaned before being mailed. In excellent, functional condition. We've used Grove Co. for years and like them a lot, but it turns out I've accumulated quite a few of these over our time using them. I'll include a few new bottles of extra concentrate as well! From the Grove Co site: Plastic-free and crafted to be sustainably powerful for a healthy home and planet. It’s designed with Grove Co. cleaning concentrates in mind, and it’s sustainably crafted from responsible, lead-free, partially recycled materials for the long run to help you clean and care for your home without the plastic waste. Plus, it’s dishwasher-safe and replacement spray nozzles are available on the Grove Co site when needed. Each bottle holds 16oz - you add the cleaning concentrate and then top it off with water in this Grove Co. glass spray bottle. Shake it up to get going. All Grove Co. cleaning concentrates are at least 94% plant-based and 100% naturally fragranced, so you won’t find harsh chemicals in them like you will with other traditional cleaners that are packed primarily in plastic.
