>>>Hmm, see, I have some tweezers from a manicure set but I don't wanna crush the stem of the plantlet.
If you aren't too rough or careless, I'm sure it would be OK to use the one you already have. Just make sure it's clean and all that.
I used the one that came with my Swiss army knife, worked just fine. If you don't have one, ask around, as I'm sure you'll know at least one person with a Swiss army knife, or other such multipurpose knives.
Or you could always pop over to your local drugstore and buy one, shouldn't be more than $3 or 4.
Good luck
