We are partnering with Slimy Unicorn Customs to sell their slime. This slime will be sent out as a surprise theme/color in 3 1/2 oz and 6oz. options. If you give us a first and second choice color/theme, we will try out best. There are holiday-themed, glitter, cloud, color shift, galaxy, fishbowl, metallic, butter, etc. There is a surprise in each slime jar to go with its theme.
