Around 25 pounds of glue and more than a month of preparation went into Crystal and Geneva Phillips’ concoction — slime.

The mother-daughter duo of Maui Slime Co. will be selling their goo at the sixth annual Hawaiian Airlines Made in Maui County Festival on Friday and Saturday.

Designed for the younger crowd, the slime is a thick, gooey and stretchable substance that has been a hot plaything for several years. The Phillips’ slime rivals Mainland company brands in big box stores with variations, including Fruit Loops slime and Strawberry Milk slime.

The most popular, Mocha Boba Tea slime, contains handmade boba balls made from baked polymer clay inside the mocha-colored goo. Most of the slime are scented.

The mocha slime was designed by Crystal Phillips’ oldest daughter, 15-year-old Edana, who started the business with Geneva, 12. The elder sister has her own beauty products business.

The unique, colorful and fragrant slime will join the mix of more than 140 Maui County small businesses at the Maui Arts & Cultural Center. There will also be food trucks, entertainment and giveaways.

“This year’s festival literally has something for every age, gender and cultural background, and we encourage everyone to come out to the MACC (Friday and Saturday),” said Maui Chamber of Commerce President Pamela Tumpap in a news release.

The chamber presents the festival, which is supported by the Maui County Office of Economic Development and its title sponsor, Hawaiian Airlines.

The festival offers a springboard for local companies to take their business to the next level by being able to unveil new products, meet with prospective wholesalers and connect with new customers, the news release said.

This is Maui Slime Co.’s first festival. It will join 35 other first-time vendors, who will offer jewelry, furniture, handbags, baby clothes and gear, candy and sweets, succulents and beauty products, to name a few.

The old-timers include Kanemitsu Bakery, offering its famous Molokai bread; Matsumoto Studio; Maui Fruit Jewels; and Wrappily Eco Gift Wrap Co., who all have a few years under their belts at the festival.

Crystal Phillips said the family feels “very blessed” to participate in the festival.

“We feel so honored to be a part of something that honors local small businesses. We want to be able to reach as many people as we can with our unique products and connect with our community,” she said.

The mom said the family would “love” for other local businesses to sell their products. Currently, Maui Slime Co. can be found on the crafters and homemade products e-commerce website, Etsy. The Phillips’ also sold their products at the Maui Swap Meet this past summer.

“If we can reach larger markets, we would love to expand that way, too,” Crystal Phillips said.

The Phillips girls actually began their business by making squishy toys by hand. Squishes are soft, colorful and made to resemble food or animals. The Phillips’ squishes are made out of foam and flex foam.

The sisters began cutting foam into shapes and painted them one summer. They got good at it and opened up an Etsy shop in 2017. They made 40 sales.

When January 2018 came along, the family began making slime and added it to the online Etsy site. Over a year later, the shop has reached 1,000 sales.

In 2017, the business was named “Adopt a Squishy” because they were more focused on those toys, but the family changed the name to Maui Slime Co. in 2018, reflecting the business emphasis.

Maui Slime Co. has 30 different varieties of slime in their Etsy shop. It also sells slime supplies, squishies, squishy kits and slime kits. Some squishies are purchased from other vendors and are transformed by Maui Slime Co. into something new.

As for its main seller, slime, the main ingredient is glue.

“But not all glues are equal. We have found specific glues we really like and have stuck with those,” Crystal Phillips said.

The slime is colored with food dye and sometimes acrylic paint. Scents found online are used in the slime concoction.

Geneva comes up with most of the slime varieties. “As a mom, I have ideas, too, so we often work together,” Crystal Phillips added.

The slime comes in four different sizes of clear labeled containers — 2 ounces, 4 ounces, 6 ounces and 8 ounces. They are priced from $4 to $10 locally and $6.50 to $12.50 in the Etsy shop, where they offer free shipping in the U.S. Squishies range from $5 to $10.

Do-it-yourself kits for squishies and slime will be sold for $10 at the festival.
