Yes, they do have clay occasionally, but not frequently due to it's high demand. I have only seen one other Daiso stock it somewhat frequently, and that's the one on Sawtelle Blvd. However, you will want to call first to see if they have it.
No but you can buy some ingredients here to make slime. For sure they do not sell borax or contact solution. They definitely sell glue. If you have a special slime recipe and need to know about if a certain ingredient is sold here i can let you know
