The Product name and picture is correct, it is a set of 3 (!) Arrows as accessories for Hasbro Nerf Rebelle arc (B0344EU4).
ATTENTION!
The product description is wrong, ie by another product - the so-called Nerf Blaster Rebelle (like a gun, no bow)!
See:
Supplies for the Nerf Blaster Rebelle: The set includes 12 message Darts with flight range of up to 20m for transmitting secret messages. With special pen for multiple labeling and decoder.
One thus gets here 3 arrows to Hasbro Nerf bow, not 12 arrows (darts) for a gun for the price of just 10, - Euro.
Overall, not cheap, but the quality of the material (carbon fiber stems) and the workmanship are good.
Conclusion:
One star deduction for the princely sum of about 3.33 for an arrow and the false / misleading product descriptions.
