I found a set of glass prisms of different lengths--exactly what I wanted. Price was excellent, quality excellent, service excellent - great experience. The prisms are made from high-quality glass with nicely finished vertices. Delivery was wonderfully prompt with appropriate packing to keep them protected. I would look to Indigo first for any materials for cool teaching materials, chem/physics lab stuff to play with at home (or elsewhere), etc.

The prisms were securely packed; each in its own box; then within a larger box surrounded by a bubble wrap container. Delivery was prompt (within 5 days of the order); and the product was as advertised.
