Hello, 

I am confusing that there are two different style of the Cart Bag with TB4CT5 model number.

Two different things,

1. pen holder location on left side of the bag.

2. the number of the supports at bottom of the bag. some has 4 (Blue) and some has 6 (Black).

Can anyone tell me is it different year product?

Also, some black bag has 4 supports at the bottom.

Please someone advice me?

*** I just bought a Black color bag but has only 4 supports not like the picture ***
