I wish they had more of the water bead feel then just the plastic the beads are in. There’s a lot of free space in some of them. They are ok quality.Pros:I really like how thick these are when they arrived, I don’t have to worry as much like I did with other competitors brands. These seem to be toddler throwing proof (always supervise when young children use these)I wouldn’t recommend for sensory play as you can’t really ‘feel’ the beads like in thinner cases. I also like the different size ‘beads’ in a few of the smaller shapes.Cons:Some of mine arrived melted/liquid & the weather was not hot. The package was put in a shaded spot. Also, my star shaped one will not allow the beads to move around to the points, whomever packaged the bead inside didn’t press out the air for them to float around freely. I’m super bummed out ?I have some students who will engage in learning with these items. I love them!I did try to email the company to find out if they offer the same product in letter shapes but the email did not go through.My toddler busted one by accidentally stepping on it. I supervise her closely with them since I know how easily they can be ripped open. Or bit open. & I don't need my baby eating little gel beadsQuality is fine but we had two X’s and no number 4.I only received 8 in the Box it clearly states that there is 12 pieces. Can someone contact me too get this corrected.Other than that my Autistic grandson loves them. He carries then call over.My Autistic daughter just loves these! They are of great quality! They are strong enough and so not break when she chews on them. The shapes are perfectly shaped as she is able to identify each shape for me. As well as the water beads are their true colors as intended and the plastic is completely clear and see through and after having them for weeks there are no scratches or bite marks on them. I actually am going to order another set for back up if she were to misplace one. She used them each day for her online summer schooling! I am very pleased with everything! A must have!Nobody liked them, they did not mush around or feel good in the hand. Sorry.
