Verá belos cristais vermelhos ao cultivar os impressionantes cristais de 2.75 de largura neste kit não tóxico e seguro para crianças. Inclui instruções passo a passo.
We followed the simple instructions and the crystals grew into a beautiful, deep ruby red color that looks amazing in the sunlight. The kit was completely mess-free and the crystals formed exactly as promised. Definitely a fun and educational afternoon project.
My son was so excited watching the crystals form overnight—the step-by-step instructions made it super easy to follow. The deep ruby red color is just beautiful, and I love that it’s non-toxic so I don’t have to worry.
