Grafting Tool - Chinese
The Chinese Grafting Tool is very easy to use. Simply insert into the cell of a larva of the right age and scoop up the larva. Insert it into a queen cup and push the plunger. It seats the larva very well.
If you are thinking of Grafting larva and making your own queens, the JZ/BZ Grafting Frame combined with the JZ/BZ Grafting Cups are great and easy items to use. Alternatively you can use attach the Hair Roller Queen Cup to a frame and graft into it.
