LOVE this stuff. The rainbows are so much fun. My nieces and nephews love playing in them. I have not been able to get them to stay on the window without taping them but double sided clear tape works well. I also love the privacy factor with them as they do muffle the view.

This was a waste of money. This was a wrinkled piece of cheap plastic that can not be used as intended. This is going out like all garbage is supposed to

Perfect! I love how durable it is. I was afraid that it'd be to fragile for crafting with, but it works like a dream!

I plan to use this for making decorative candy. I have not yet used it. It does, however, appear to be the right material.This is closer to 5x10 than six inches by twelve. If you need that exact area, this won't work. It's also a lot thinner than I expected, more like a mid-weight cellophane than a sheet of plastic. I expected something more like the pages you use for overhead projectors, though nothing in the description suggested that.Others have complained about crinkling or creases. Mine came perfectly flat. It was packaged in a heavy, flat plastic bag, then inside a padded Amazon envelope. (Frankly, the plastic baggie is thicker material than the product.) They may have gotten better about the packing and shipping or I may have gotten lucky, I don't know.All in all, you can probably do better for this amount of money.

I am tired of sellers selling junk. Read the reviews, listen to the 1 stars.1) packaging was perfect, but the film was full of wrinkles and tiny dot holes.2) this stuff didn't workI wad excited to make fancy chocolate for a birthday cake. Instead, I have to reheat the chocolate and just do something else. Wasted hours.

La malla viene dentro de un sobre de celofan lo cual no proteje a la malla ainqu este sobre este en una caja, el sobre llega doblado lo cual efecta ya que la malla llega con muchos dobleses en vez de empacarlo en un cilindro de carton, lo lamentable es que la mayoria de los comentarios son en este sentido y Amazon no mejora su metodo de empaque.

Ein sehr guter Kauf. Leider war die Ware bei der Lieferung beschädigt. Guter Verkäufer. Alle Fragen wurden schnell geklärt.

Il y a tromperie sur les réelles dimensions de la marchandise, de plus la surface de la feuille n'est pas uniforme. Frais de douane de 9€.
