Say a class of 20 students...one kit per student?** A: I wouldn't. The peices are strong when together but there are a handful of screws that need to keep their place. Once the screw threads "bite" into the plastic once, the strength of the attachment will lose alot of integrity if taken out and returned. Also, there are some adhesive pads that the "fingers" use for traction/purchase that won't peel off very well. I'm afraid that the pieces very likely would break if carefully taken apart and reassembled. I'd go as far as saying that it's likely that you would need to purchase 24 for a class of 20 to insure a surplus of "extra" parts for any that may break during assembly. Good one time assembly project though. Thank you for being a teacher. I hold teachers in the same regard as first responders as heroes. Bigs hugs for you. **Q: I am missing a P2 screw, this toy was a gift, how do I get a replacement?** A: I haven't had to contact their support line.........buut, the p2 size screw is pretty common.....if you have any old electronics collecting dust, you can probably salvage one from any old tech laying around. **Q: A P2 screw is missing, can you send one please?** A: We are also missing that screw. We're you able to find a replacement for it? ## Customer Reviews ### ⭐ Review *by J***N on 25 July 2024* dont trust the seller ### ⭐⭐⭐ Review *by G***C on 3 December 2022* While the parts in the box is all complete, the box is dented and the seal is broken.
