Another Daiso brand, "Complete", has a similar cover design but does not match up in quality, though the range of their paper products is wider compared to "Combine". Encouraged by a review by a fellow member in SFPL, I decided to try the "Complete" brand again, in hopes that their quality have improved.
The focus of the following test, is the comparison of the bleed through resistance between "Combine" and "Complete", B-line 40 sheets paper product. The main ink used is Sailor Bung Box's Ink of the Witch, and the pen is a Monteverde Invincia Titanium with a Fine nib
Combine is still much more fountain paper friendly paper hands down. With hopes of redeeming the Complete brand, I also tried Parker Blue Black in a Parker 51 Fine nib, as well as a Platinum cartilage in a Plaisir 3.0 nib.
It seems that Complete will still work with dryer inks like Platinum and possibly Pelikan 4001, but I'll personally stick with Combine for now.
