I bought this syringe for use with sugar paste (I did the test !!!) .. I confirm that this syringe is not at all made for that !!! Irrespective of the use that is simple (you just have to place the tip desired after the syringe and screw it!), The quality of the syringe (more than average!) Is not at all suitable for food use because very dirty inside! (I did not dare wash it because I truly believe that it will rust!). So I think for dough fimo it should not be much of a problem (well condition wipe with a cloth before use if you do not want your dough is dirty!). For the price, you can afford to take the test!
