mala calidad. But again form fits function here. Maybe they will see this feedback and stick to a simple soft leather or leatherlike strap for ankles and toes. It?s ok. To the makers of this case: let me know if you do produce a two piece case! Easy to clean and fast to just slip on. Additionally, the hihats and other high sounds very crisp. Saved myself $150 repair fee by buying all the parts myself on Amazon. These are adorable for my 7 yr old. I dont think they make a difference in grip in terms of staying in the ear, but they are easier to pop in and out of the case, and distinguish mine from my husbands.
