    Judging by the way the boxes are wrinkled, they were brought by ace ventura, but the bags were without damage, came in three weeks, the quality is excellent, the store recommend.

    Great bag. Quality is decent. I did not regret buying. The box though crumpled, but nothing is damaged. Inside the headphone extension 3,5mm. Zippers and velcro are excellent. Delivery on time. I recommend this store.

    Quality excellent advise

  11. A***v

    Perfect quality! Very-very good stuff. Will add some photos on bike later. Seller is very good, all as described. Boxes are a bit wrinkly but bags themselves are straight. Cap-peaks are straight also Thanks!!!

  12. L***t

    Great! Fixes to the bike very tightly. A lot of space inside. The phone is reactive through the plastic. It’s the right width so that it doesn’t touches the knees.

  13. M***a

    Recommend. Super fast delivery 🙂

  14. A***o

    Very good handbag on the frame. Seller thanks! I recommend.
