6 pack butter slime kit for girls and boys. Warm Tips-Can Not Eat. Wash Your Hands Before and After Playing with Slime. If It's a Bit Dry, Add Some Glycerin or Water and Roll It. If It’s Sticky, Put It for 1 hour In The Refrigerator or Put Some Baking Soda and Rub It. TIP:The product is a little frozen due to the low temperature, don't worry, soak the jar in hot water for a few minutes, or rub it for a few minutes before playing to make it soft and stretch, if there is any Questions can feel free to contact me at any time.
