DENT_EX Interdental Brush L Size 5 sets of 4 brushes per box, and 1 set of 3 brushes per box. *I bought these in bulk, but I no longer need them, so I am selling them. Product Description This interdental brush offers excellent durability and operability. ● Uses ultra-alloy SA wire that is resistant to breakage It is hard and springy, making it difficult to bend and achieving excellent durability. ● 110-degree angle for easy insertion between teeth Provides high operability even in the molar region. You can brush from either the cheek side or the tongue side without bending the brush. ● Easy-to-adjust insertion angle and easy-to-hold holder The 85mm long holder pen grip is easy to hold and easily reaches the molar region. The crystal-cut non-slip grip allows for fine adjustments to the angle to the interdental space. The round holder allows use from any direction without being fixed at a specific angle.
