It appears that the specific brand name "Ganhou" for a "Tri-Pack In One Brush" is not widely available or indexed by major retailers in Pakistan, or it might be a very niche/smaller import brand.

? Potential Product Interpretation

The term "Tri-Pack In One Brush" most likely refers to one of two common types of toothbrush products:

A 3-Pack of Standard Toothbrushes: The most common form of a "tri-pack" is a bundle of three regular toothbrushes from a well-known brand like Colgate, Shield, or Oral-B.

A Triple-Sided Toothbrush (The "In One Brush"): This is a specific design (often used for children, special needs, or deep cleaning) where the brush head has three sets of bristles angled to clean the top, front, and back of the tooth simultaneously.
