They're not super strong but my kids love them! Can't beat the price. I wash them every week and other nights the kids hang them up to air. The only downside is that they come in floral packs for both boys and girls. I have 2 boys and a girl. 2 boys could share the boys colors but they were too small for my girl so I had to order something else for her. It spent 2 pairs of 6 packs. It is better to sell boys colors in one pack and girls colors in another rather than mix them.
