Me agrado el kit sobre todo que trae muchos pares de electrones libres y me ha sido de utilidad para las clases de estereoquímica. Buena relación calidad-precio.

My students use these to build models of molecules and compounds. It provides them with a visual of a concept that otherwise would be rather abstract to them. This is a quality product, and it comes with everything the students need to build their models.

Kit arrived quickly and safely. I am impressed with both product and service. Thank you.

I ordered this set for my chemistry class in my homeschool coop and it was missing 3 purple pieces with 5 holes to make a trigonal bipyramidal model. I contacted the seller and asked if they can send me the missing pieces as I need them for my class. Instead of sending me three 5-hole spheres, they sent me another complete set! I’m truly impressed and grateful for their amazing service. As for the modeling kit itself, it seems really well made. The holes are just the right size, not too tight and not too loose. And I choose this kit because it had more of the 5-hole and 6-hole central atoms which are what I needed for my class.
