pengxiaomei 2 Pack Square Cube Prism, 18 mm Refractor Crystal Prism for Science Teaching Physical Lessons

These are very pretty. Unfortunately both arrived damaged. The packaging was a thin plastic envelope and the cubes were wrapped in a single layer of tissue.

Two damaged cubes out of six

These are glass cubes with a prism built inside such that each face of the cube will refract a different colour of light. Makes for very interesting observations. Now I have to figure out how to turn this into a physics lesson for my kid !

Item received damaged...not wort returning for £8 but I understand this is a common issue with these....as they are not packed properySo take my advice and dont waste your money

We have these on the bedroom window sill so that during spring and summer we wake up to beautiful colours dotted about our room. They work like a charm.

Gorgeous little cubes let down by shoddy packaging. Bought 3 pairs and they all arrived chipped and one pair was mismatched. This isn't the first time I've tried to buy these and every time they arrive loose in a plastic bag with no padding at all. I thought by buying a Prime set they would have proper packaging but sadly no.... Don't really want to buy the ones in presentation boxes because they are so overpriced. Just want a bit of bubble wrap round my cubes. Sadly a waste of time.

Suggest buyers note the size before purchasing.

Arrived in an unpadded Amazon envelope, but were tightly held in place, no movement, no damage. Each was individually bagged and then together in a much sturdier bag. Even unwrapped the colours captured in sunlight are wonderful. Good STEM gift for children to explore light.
