The Círculo Amigurumi Stuffer is a tool from the Brazilian brand Círculo, designed to facilitate the uniform filling of amigurumi dolls with silicone fiber stuffing, preventing lumps and ensuring a more uniform and firm finish on the pieces. Its elongated shape allows it to reach narrower areas, such as the arms, legs, and antennae of the figures. It is ideal for those who make amigurumi regularly and seek to optimize the stuffing process. It is compatible with Círculo brand silicone fiber stuffing.
