Rainbow Spectrum Secret Viewfinder Review

Perfect for our kids spy party and can also be used with any study sets (for teachers) or kids to create their own secret hidden messages.

Used for my granddaughter's quest game. I wrote my clue in blue with a red pen or marker to hide the clue. The binoculars gave a fun flash of a simple clue.

Our group decided on a spy mission where we will use these decoders to find clues. It's a great price, good quality and they arrived as quickly as I had hoped.

This worked great for DIY quests. He wrote in invisible ink, put clues in balloons - these binoculars were on the table. This led her to the next clue. It was a complete success

We used this to discover clues in the quest. They were good value for money. The viewing area was big enough for our project and everyone could uncover all the clues. I would buy them again.

Loved this for encrypted messaging at my girls birthday parties. I printed the messages in light blue ink and then scrawled them with a red pen so you couldn't decipher the message until you used the decoder. Worked great! Sent them invitations from girls.

Rainbow Symphony Spy Glass - Secret Reveal Lens Decoder (Pack of 25) Contains 25 cardboard and red cellophane decoders that combine to form a magnifying glass. Inexpensive and each decoder can be used multiple times by students.
