Tweezers come in many variations - length, curve, shape of the planting tip, closing pressure ... this is the downside if you must buy them online, un-held; in-store you can find the one that fits your hand & feel ... then practise planting toothpicks or coarse threads or whathaveyou
I dislike strongly sprung tweezers, mine are very "soft" & smooth.
Feel the plants with your fingers first to suss out plant "strength"
