| Those particular spray bottles are Zep Professional Sprayers. I got mine at Home Depot for $3.79 apiece. They're good sprayers, but I personally don't like the long section of plastic in between the sprayer itself and the bottle. It feels awkward. The two bottles to the left of the Zep bottles in my pics are what I bought yesterday. 89 cents for the bottle and $2 for the heavy duty chemical resistant sprayer at my local detail supply store. I love them. I only got the Zeps because I was in a hurry to get some and HD is right around the corner from me.
Costco and Sam's both sell bottles. I believe they are sold in packs of 4. |
