4 oz. jars in plastic are perfect for holding scrubs or bath salts and make a lovely gift. We love these because they won't break in slippery situation like your shower and the wide opening is great for scooping from. Refill over and over with your favorite scrub.
What about EOs and plastic? Heavy duty PET plastic is suitable for essential oils when used sparingly. You may choose to avoid using citrus oils in plastic as it is the most likely to break down any plastic.
