These custom pre-presses are sized to fit Rosin Evolution 2″x4.5" screen bags.
This mold is a simple yet effective method of quickly compressing your material for easy insertion into the bags before pressing.
Just add your material into the compartment and press. You will get a perfectly sized slab to fit inside the bag.
This tool will not only save you time but will help you achieve more uniform results.
Dimensions: 3,81 x 8,25 x 5,08 cm (1,5 x 3,25 x 2" inches)
For best results we recommend 15-25 gr. of material.
Hold the compression for about a minute. Time will help solidify the brick, making it less likely to re-expand when pressure is released.
