Product Description
These loose prism sets include magnetically attachable handles that permit easier and less cumbersome counter-top storage, transport, and use than devices with permanently attached handles. The magnetically attachable handles are fast and simple to attach and detach. Strong rare-earth magnets hold the devices firmly on the handles, yet are easy to remove.
These high-quality prisms are used to measure the deviation in strabismus. It is important to conduct polarized testing through prisms that are known to cause the least interference with polarization.

My wife got these for our grandson and he loves when she gets these toys out. They build garage bays for his toy cars and also houses. Initially he waited for the build-up, then he would crash them down and laugh while doing it. Times have changed, and now he drives his trucks and cars into their own garage bays. He also says the colors of them while playing.

These are great for all ages. There's a large age gap between my kids and they both enjoy building with these. They hold up very well. The magnet strength is pretty good depending on how you build your structure. We have built "castles" and it holds dolls. Comes with a variety of colors.

My 2 yr old grandson sat down in the middle of his Christmas gifts and started building. He had to be reminded to look at and open other gifts. He kept his eyes on the building magnets though as his mom scooted them out of the middle of the room into container.
