We have ~30 sets of plastic and metal tweezers ideal for sorting invertebrates gathered in pond dipping or leaf sampling events.
These tweezers are soft enough that they will not harm any invertebrates that are handled correctly.

If you are organising a pond dipping or invertebrate sampling event we also have butterfly nets, magnifying bug tubs, hand lenses, microscopes white sampling trays and various other useful equipment. These are listed separately.
