Use these frequently at my job. The only bad thing I can say, is that I wish I’d noticed the smaller ones mixed in. I already had small. Fun stuff.On the tile floor, in the sink (bath time), in the bath tub, on the windows, on the flat table... these stick to flat surfaces, and to each other! Honestly my husband and I have as much fun with these as our 10 month old... looking forward to squigs when she is older hahaMy grandbabies 6 & 8 months old love playing with these, and the big kids (parents) had a great time too!My son loves these. Very durable and easy to stick to a window or fridge!These are wonderful!!!! My 2 yr. old grandwonderful can't put them down. They are used in the bathtub, in the living room, in the playroom, on the train table, on the windows, walls, counters, cabinets doors and anywhere a flat surface exists. Love, love LOVE these!I got this for my 7 month old as she was starting to pull herself up to standing everywhere including the glass door. I knew that strategic placement of these pipsquigz would help her fine/gross motor skills and balance as well as capture her attention and help keep her face off the glass (instead she likes to grab the squigz and once she pulls it off, she promptly chews on it!). These did not disappoint. I even used them on her high chair tray to keep her entertained while I’m getting her food ready! I especially love this variety pack!1/4 of the bag are your standard squigz; Those worked well and the suction were great.Another 1/4 of the bag were long duotone pieces that don't suck as well. They don't even have a logo on these which makes me feel like they're some discount off brand.Finally half of the 75 piece set was filled with miniature versions of "squigz" that are all choking hazard for children. My 1 year old can fit the biggest of the miniatures (3 suction cups) in his mouth.Although you get 75 pieces they were 2 sizes and didn't snap / pop together.Me fascinó y a mi bebe también. Super dinámicos los.jueguetes.
