Jumbo Nuts and Bolts Toys 52Psc for Toddlers Preschoolers Kids, STEM Educational Montessori Building Construction Screw Matching Activities for 3,4,5 Year Old Boy and Girl.

Love these for my classroom. Durable and a great price.

Perfect for a child sensory skills. I purchased this for a daycare

Bought for two year old grandson to add to workbench. Plays with it often for long periods of time. Encourages much creative play and fun learning time. Give many opportunities to pratice colors, matching, and numbers. Very durable, brightly colored, and large. Does not present choking hazard. Highly recommend.

These are great to put on a parrots cage. They love to unscrew the bolt from the nut. Unfortunately, only one of the sizes fit his cage, so I have alot of extra. But he also likes to use the screw side as a cup. He can get a good drip on the shaft and dip it is his water bowl, then drink out of it like a martini glass!!

This puzzle block toy is very entertaining and amusing for my son. It also helps him learn because he can pair the same colors together or shapes. The colors are nice and bright and it’s well made without sharp edges.

My baby wasn’t a fan of this, not only are certain pieces only meant for other pieces, there was an uneven amount. The pieces are also very hard to screw on and can easily cross thread.

My niece has been very interested in twisting things and always tries to play with bottle cap but it makes me too nervous, even when I am watching her closely (those little buggers can be quick) these were a great alternative for her to keep getting her practice. I love how large they are so I don’t have to worry about choking.

Let me first say I dislike the description for these nuts and bolts for kids! These are wonderful tools for play idea expansion! Children will come up for a multitude of uses and learn via their play, let them decide how to use these and they will LOVE them. Wonderful product!
