## Questions & Answers

**Q: How thick is the foam to keep the marbles from falling off or is there a lip that I can't see from the pictures?**
A: The foam is very thick ~1in? and there is clear plastic guard attached to each piece that keeps the marbles from falling off. Really fun, although pieces are bigger than the pics suggest and it takes up my whole bottom of my fridge. Kids had 2 hrs of fun playing together Xmas morning!

**Q: Which of these size magnetic boards work... 3×4, 3×5 feet?**
A: 3 x 4 is good

**Q: Will 2 ft ×3 ft metal board be too limiting? We don't currently have a magnetic fridge.**
A: Yes.  That is too small a space   I use my metal door.   My daycare kids of all ages play with magnets.  From 3 to 12 one of the best toys ever

**Q: does it have enough pieces for 5-6 kids (5 year olds) to play at the same time?**
A: Not really.  I think it would work maybe up to 4 if the magnetic board is large enough for the students to have room to use the parts.  I used with 4-year- old's and I only let 2 students use it at a time.  It also does not hold up.  My students wore it out the first year.  The class I used it with, knew how to use it and took care of it. They liked it and used it a lot.  I was hoping to have it longer.
