Rainforce sells glass mason jars in bulk packs for home cooks, crafters and anyone who loves a tidy pantry. A mason jar is simply a thick glass jar with a screw-on metal lid, and the design is so useful that people fill them with everything from strawberry jam and overnight oats to homemade candles and party favors. Rainforce jars share the same basics across the range: clear, lead-free glass and metal lids with a plastisol liner, a soft rubbery ring inside the lid that presses against the rim to seal it airtight.
The four sets below mainly differ in jar size (8, 12 or 16 ounces), how many jars come in the box, lid color (silver or gold), and whether gift extras like tags and twine are included.

Rainforce Mason Jars 12 oz 20 Pack for Everyday Kitchen Storage
The Rainforce Mason Jars 12 oz 20 pack gives you twenty 12-ounce jars with silver lids and twenty labels. The glass is described as thick, lead-free and 100 percent food safe, so the jars work for both food and drinks. Each lid screws on with a plastisol liner for an airtight seal, which keeps dry goods fresh and drinks from leaking.
They have a regular mouth, meaning the opening is the standard, narrower size rather than a wide mouth, and Rainforce lists it at 2.5 inches across. That is wide enough to spoon in oats or pour in sauce and to reach the bottom with a sponge. The listing says they can be washed by hand or in a dishwasher, though the lid care note is cut off in the listing. One small error: a feature bullet calls these pint jars, but a pint is 16 ounces, so these are smaller than a true pint.
Twelve ounces is a handy size for overnight oats, a single serving of salad dressing, homemade granola or spices bought in bulk. This set suits a home cook who wants a lot of matching jars for the pantry. If you plan to give jars as gifts, the gold-lid sets look more festive.
Rainforce 16 oz Mason Jars for Pickles and Drinks

Rainforce 16 oz Mason Jars with Silver Lids 15 Pack Pint Glass Canning Jars
Price and specifications are read from the Amazon product page and can change.
Rainforce 16 oz Mason Jars
Best for: Pickles, drinks and larger batches
Pros
- True pint size at 16 oz
- 15 jars with 15 labels
- 5-inch regular mouth
Cons
- Fewest jars per ounce of storage
- Care instructions conflict
The Rainforce 16 oz Mason Jars set includes fifteen pint-size jars with silver lids and fifteen labels. Sixteen ounces is a true pint, the classic size for pickles, jams in larger batches, iced coffee or smoothies, and soups for meal prep. The listing names honey, jam, jelly, meal prep, pickles and spices as recommended uses.
Like the 12-ounce jars, these use thick, lead-free, food-safe glass, a regular mouth with a 2.5-inch opening and metal screw-on lids with plastisol liners. The labels help you mark contents and dates. The care instructions list both “dishwasher safe” and “hand wash only,” which conflict, so washing the lids by hand is the cautious approach.
This set suits first-time canners and meal preppers who want bigger jars. For single servings or small gift portions, the 8-ounce or 12-ounce sets are a better fit. If you are comparing with other pint jars, our guide to classic pint mason jars covers the size in more detail.
Rainforce Mason Jars 8 oz 30 Pack for Jam and Party Favors
The Rainforce Mason Jars 8 oz 30 pack is the biggest set by count: thirty 8-ounce jars with gold lids. The description explains the size simply: 8 ounces equals a half pint, or a quarter quart. The set includes thirty sticker labels and a white marker for writing on them.
These jars share the family features: lead-free, food-safe glass, a regular mouth with a 2.5-inch opening, and metal lids with plastisol liners for an airtight seal. The specs list them as dishwasher safe and reusable, though they also say hand wash only, so gentle hand washing is the safe bet for the lids. The description also calls them stackable.
A half-pint jar is the traditional size for homemade jam, jelly, honey or a small candle, which makes this the best set for wedding favors, holiday gifts to neighbors or a bake sale. The gold lids add a finished look without any decorating. For even smaller portions, see our guide to 4 oz mason jars. If you want larger servings, the 12-ounce sets are the next step up.
Rainforce Mason Jars 12 oz 6 Pack as a Ready Gift Set
The Rainforce Mason Jars 12 oz six-pack is the smallest set by count, but it is built with gifting in mind. Along with six 12-ounce jars and gold lids, it includes six labels, six kraft paper tags and 10 meters of natural jute twine, so you can tie a tag around each jar and hand it over.
The glass is listed as thick, BPA-free, lead-free and food grade, with metal screw-on lids and plastisol liners. The listing says the jars are dishwasher safe but recommends washing the lids by hand. It also describes these jars as wide mouth, while the title calls them pint jars. The listing does not give the opening size, and 12 ounces is smaller than a pint, so treat those labels with some caution. Rainforce says each set ships cushioned with pearl cotton in a sturdy box.
Rainforce names honey jars, candle jars, jam, spices, dry goods, DIY crafts and party favors as uses, which makes this a good pick for crafters or anyone making a handful of homemade gifts. If you need many jars for a big event, the 30-pack or 20-pack is more practical.
How to Choose the Right Rainforce Mason Jars
Match the size to the job. Eight ounces suits jam, honey, small candles and favors. Twelve ounces suits overnight oats, dressings, snacks and medium candles. Sixteen ounces suits pickles, drinks, soups and bulk pantry goods.
Choose the pack count. The 30-pack and 20-pack are best for big batches or events. The 15-pack gives you a solid set of pint jars. The 6-pack is best for a few special gifts.
Pick a lid color. Silver lids look classic in the pantry. Gold lids, on the 8-ounce 30-pack and 12-ounce 6-pack, look more decorative for gifts and weddings.
Look at the extras. Every set includes labels. The 8-ounce set adds a white marker, and the 12-ounce 6-pack adds kraft tags and jute twine. If you prefer plastic lids for daily storage, our page on plastic wide mouth jar lids explains the options, though check the mouth size of your jars first.
Care for the lids. Most listings say the jars can go in the dishwasher, but several recommend hand washing the lids. Hand washing helps protect the liner that creates the seal.
