Wide Mouth Polystyrene Jar: This glossy, rigid, sturdy wall clear jar will make your bath scrubs, lotions and other products stand out with full visual appeal. We do not recommend that you use polystyrene jars for packaging bath salts which contain fragrance or essential oils as these oils may eat away at the jar (use at your own risk). We have found that bath scrubs which include salt or sugar, vegetable oil and either a fragrance or essential oil hold up very well in these jars IF you prepare the mixture first in a large, separate bowl and then pour the finished product into the jar. The finished mix usually allows the vegetable oil to float on top of the scrub. Do not prepare the mixture directly in each jar as this will affect the clarity of the plastic! Included is a smooth white plastic, flat, unlined screw-on lid. Even though we provide the above tips based on our findings, please test one jar before filling several jars and watch how your product reacts to the jar. We have a “no returns” policy. Finish: 53/400.
