Straight to the point info:

• Easy-to-load, 6 sheet,  4x5 developing reel.

• Soft loading, now integrats very low friction PTFE tube in the back wall

• Works great with manual inversions and rotation on B’s processor

• The Mk3 version brings new geometry designed from the ground up for an easier film pre-wash, reel rinsing and drying.

• Made of ABS plastic for chemical and heat resistance.

• Top rack of dishwasher-safe for cleaning any residues especially if you use it in E6.

• 3D printed in USA.

-The smaller sizes like the 6.5x9cm and the 2.25”x3.25” reels comes as a set of two reels (6 sheets each developing up to 12 sheets)

-4x5 Fits in a Paterson 3 reels, two in a paterson 8 reels.

-5x7 fits in a paterson 5 reels

Building upon B’s reel mk2’s original design legacy, the Mk3 was designed from the ground up.

Holding a sheet of film is easy to do, holding it the right way to provide the best possible development is another and the Mk3 reel delivers the best results, both in rotation and inversion.

The large surface of a 4x5 sheet and the geometry of the reel has a huge impact on how even development occurs across the sheet. Obviously some sort of structure is required to hold the sheet in place but this design reduces the structure to its minimum,

allowing the chemicals to flow onto the film in the best possible way.
