Musiclily Pro Urea Resin Plastic Slotted 42.3mm Precision Bass Cejuelas Fondo Plano para Bajo P de 4 Cuerdas, Juego de 2

Very, very small

Did exactly what it was expected to do. Requires a slight amount of sanding to fit in the slot, which is to be expected. Great value for the money

2 Plastic nuts, had to file to get them to fit my bass (as expected). There's really not much else to say. They work.

Worked out great

These nuts are very fragile. I had to go with these because these are one of the only flat bottom nuts for precision basses on amazon. I have filed several nuts in the past ad issues. Both of these broke very frustrating. Went with a tusq nut which requires a lot more filing to make it fit. So beware these nuts are like glass.
