BELLE VOUS K9 Crystal Triangle Prism - Photography Triangular Prism Refractor with Velvet Pouch & Cloth - Clear Lens Glass Prism for Light Spectrum Physics - Rainbow Effect Photo

While the box it comes with is very flimsy, the lid does not seal and is generally poorly made but it does protect the prism. The prism I am really happy with, no chips, no smudges, and is good quality.Overall happy with the item, just wish it had a better box or sleeve as I will be using this for photography and so will be travelling a lot with it.Just be careful if you smash this or chip it in any way as the glass is very sharp

Comes in a nice presentation box with pouch.Outstanding quality

The crystal prism itself is a good product. I had to give it a fair bit of a wipe down to remove some minor marks and stains upon initially receiving it. While this made the crystal prism mostly clear, I can see upon close inspection that there are still some, potentially permanent, minor stains. :/ This may be an issue for any photographers out there, however, I do not know for certain as I am not using this product for photography.The presentation (black Belle Vous containment box), however is by far the weakest aspect with the box appearing very flimsily made. It does not fully seal unless a small amount of force/weight is applied onto the top of the lid. This may lead to small amounts of dust getting inside and onto the crystal prism if left for very long periods of time. A cheap simple and small magnet underneath the fabric could have solved this easily. The crafting of the box is also slightly poor with much of the glue between the walls and the base leaking onto the exterior.Overall, while there are some poor and slightly disappointing aspects of the product (mainly the box), the crystal prism itself is well crafted with no chips, scratches or dents. If you're expecting a pure premium product for a cheap price this is NOT the product for you. If you just want a decent quality glass prism for an okay price then this is good. If I was buying again I would strongly consider opting for other listed products that were a few extra £s but looked to have much better storage boxes and glass quality!

I bought this product for artistic purposes, to better understand light refraction. It has been most illuminating and worth every penny.

The case and internal packaging was quite disappointing and cheap. The crystal was a little scratched at the edge. Overall for the money I guess was ok but they lost it trying to create a fancy case.

A nice quality item and a very speedy delivery. I could not find the pdf file to show how to make best use of the prism to get rainbow effect but got a super fast response from Tinyro with a copy. The pdf content was more basic than I had hoped but I will experiment with my grandchildren to see what we can do with other light sources.

Ordered 2 of these. One for me and one as a gift for someone. One of them was near perfect, the other had a significant defect. One of the sharp edges looked like it had been cut off so it essentially had 4 edges. There must be no quality control at all, I’m very disappointed. Especially seeing as I gave this one away as a gift so only found out about the defect much later.

Very pleased with the prism. It is made of high grade optical glass, perfectly clear. Arrived very quickly, a lot fast than expected and was well packaged. It does what it is supposed to do perfectly and is a perfect size for handling, especially for teaching refraction, dispersion, total internal reflection etc. I have not bought it for this, but for use in my photography business.

je suis satisfait du produit commander, la boite est très belle, la pochette du prisme est en velours c'est très jolie avec sa micro fibre, attention aux trace de doigt qu'il est bon d'utiliser le prise avec la micro fibre si vous ne voulez pas laisser de trace en général très satisfait du prisme

schöne Preis/leistung Mittemit der Tasche und der Box sehr Edel

Good size.

Il prisma è ben fatto e senza macchie interne, purtroppo è anche molto fragile, nonostante fosse dentro la sua scatola, cadendo se ne è rotta una parte.Conto in futuro di ricomprarlo

Le ha gustado a mi hija, como regalo de cumpleaños. Un rayo de luz. Buena refracción de rayos solares para realizar arco iris. Con un rayo laser, se observa el grado de incidencia de la luz y su refracción. Viene con un paño de limpieza, una bolsa para conservar y presentado en una caja con terciopelo. Aprecio la presentación y la calidad del producto.
