Feels like V4 on the 45° wall due to their small size. There is ample area to curl all 4 fingers around the lip on each piece. Kids would feel confident on this hold on a vert wall. People new to the sport will find them challenging at 10-20°, likely they are V2 at those angles. On my 35° wall they go V2/3 depending on how far away they are from a foot hold and what angle they turned to.
