It is normal for slime to arrive sticky. This may happen due to warm weather and certain slime textures are more likely than others to be a bit sticky. To restore it to its normal consistency, simply add a small amount of activator and knead until you achieve your desired texture. Be careful not to add too much activator, as this will result in a stiff slime.

It's common for slimes to arrive stiff due to cold weather. Most slimes can thaw out within a couple hours if you leave them in a warm place or by warming it up with your hands. In more extreme cases of stiff slime you can try the following solutions:

White Glue Base: Mix small amounts of lotion in slime and knead until your slime has reached your desired consistency.

Clear Glue Base: Keep slime in an airtight container in a warm place for a few days to allow the slime to soften up. You can also try adding small amounts of glycerin which will soften the slime. 

Always store your slime in its airtight container when not in use. Regularly activate slime to prevent it from melting completely. Wash your hands before and after use to keep your slime clean.

Don’t worry! Use a 50/50 solution of white vinegar and warm water to get slime out of fabric surfaces quickly and easily. Also works on clothes and hair.
