GuideCraftTreasure Blocks - Clear: Smooth Wooden Observation Stacking Blocks with Transparent Windows, Educational Toy for Kids

These blocks are such a fun way to encourage scientific curiosity in my kiddos! They are durable. They are a visually appealing tool to keep a collection organized.

Top quality items and amazing customer service!! Hard to find these daysWorth the investment.

Beautiful set of blocks! To put items in the blocks, you need to screw one of the sides open and then closed again. It only took a few minutes, so it wasn’t difficult by any means. I bought these for my nine month old any they’re a little bulky for him to manipulate on his own. But, they stack really nicely and he loves knocking down the towers we build for him!

Great quality. Durable enough to withstand preschoolers and toddlers dropping these on a wood floor. Great way for younger kids to safely look at things.

Beautiful. This concept is terrific. Create miniature display cases that your kiddos can place with. Very impressed with the quality. Definitely an heirloom toy.
