K Balls

I'm sure someone will be in shortly who does have an answer, but these are similar and are also in stock.

Thanks! Those are on my holiday list. I just went out and bought these from another retailer.

These are pretty great - I hope EF gets them back in stock! But they are certainly more rigid than my FF Teneo Duo and Luna Beads. I'm going to get the regular smartballs for Christams
