Eyeball Weight?

Is there any semi accurate way to weigh my buds, i dont wanna buy a scale just a one time thing. Id say I could just eyeball it but its been too long since ive bought a sac.

nah not no more back in the day when all bud was pretty much the same ya could roughly guess but with these nucleur nugs that people grow now some r just so dense that just a single small bud can suprise you and way an oz.
