It took me FOREVER to realize I could replace my giant Costco mouthwash bottle with something else. The large plastic bottle is such an eyesore that I've been putting it in the cupboard under our sink, which means it gets used less frequently, unfortunately.
Enter this beautiful swing top bottle I found at my local Dollar Tree. I ran it through my dishwasher then poured in the mouthwash, simple as that!
Once we finish off this bottle full of mouthwash, I'll give it a wash, then fill it up again.
Your Dollar Tree may not have these in stock; they go fast! I went back the next day and mine was already out. But I imagine you could use one of these decorative cork topped glass bottles instead.
