This 3-D printed crossbow comes with ten "arrows" and two elastics. It was printed by my son on his 3-D printer with PLA filament. I then glued the two pieces together and prepped it with the extra supplies. You will be pleasantly surprised with how far this little crossbow shoots the cotton swab. As with any handmade item slight imperfections may occur. Colors shown may not be exact due to differences in computer screens and camera.
