### ⭐⭐⭐⭐⭐ good quality

### ⭐⭐⭐⭐⭐ Vale la penap

### ⭐⭐⭐⭐⭐ So cute
*by K***K on 19 February 2025*

Great price, looks cute and is actually a gold color and not a weird yellow or orange or green hue, and doesn’t turn my skin green. It is a bit of a beyotch to screw in, so I just leave it in all the time. If I ever think it might be getting loose I just put my thumb on the flat back and spin the front towards my face. Only downside is if you leave it in is it kind of pokes you if you sleep with it in, so sometimes I do notice a little bit of skin flaming around it due to that. But this thing had been through the ringer, been in for months now, has be saturated in hair dye and still came clean and looks good, stayed in even when fidgeted with. Would definitely get again/more products for this company.
