How to Pick Best Detective Kits for Kids?

If you have difficulty in finalizing your selection. So, let’s go over some details to help those stuck in decision making.

There are several types of detective kits for kids as we’ve seen above. Then, the first thing is to decide on the model. Age factor could help you a lot as you can find detective toys for +3, +6, and +9. If you don’t care much about the age recommendations, you probably have a playing style in your mind. Do you want to play with your kids? Or do you want to let them play with their friends? Let’s continue with the toy types for the best detective kits for kids.

Toy Types

We can say that the primary toy type for detective concept is science kits. These sets are for imaginative and creative games with families and friends. They are very educative. You can use them for different purposes like decorating the room or teaching some detective vocabulary for a different language.

We also have other types of detective toys which are more like cosplay costumes. You can find detective hats, pens, magnifiers, crime scene tapes, goggles, sunglasses, and more.

Material Quality

Material quality doesn’t matter much for these toys. Everything is similar to items that you can find in stationaries. As they are for pretend-play, the best material is the best-looking material. You know, no one will actually solve a crime. Besides, safety will be secured by parents because most of the items in these toy sets require parental supervision because of chemicals.


Make sure you double-check online shops for the prices. Sometimes, some sellers try to sell identical toys for more expensive. If the price range is like $10-50, there should be no big surprise.

We cared about the value of our recommendations for their price to make a safe-list for you.

Age Group

Caring about age groups can mean a lot. Most importantly, safety is the first concern. Then, the dependancy of attractiveness for different age group follows. Give it a second thought if you are about to decide a product out of your kids’ age group.


Fabric is the right choice for costumes. I’ve had to find costumes for some school organizations and always ended up buying from online shops instead of hiring. Buying is surprisingly cheaper and more importantly, healthier.

Stem Kits

We’ve also given place for some STEM kits on the list. Integration of science, technology, engineering, and maths to toys for +6 is beneficial.


If you are looking for the best detective kits for kids, you won’t have many options. As I said before, Osmo – Detective Agency is the best you can buy. Still, I can suggest another strategy if it’s too expensive for you. You can collect some related items from online shops and stationaries to make your own set. This would be a good suggestion for you if you didn’t like anything on our list above. Inspecting these kits would also help you to develop your own detective-themed ideas.
