This Renia Aquilim GL is a rubber cement (Neoprene) glue that is designed for leather applications.
It is some of the best glue for many leather craft demands. It is manufactured in Germany and has been used for decades in the shoemaking world. It is designed to withstand everyday wear and tear.
It is water-based, non-toxic, and has no foul smells. The largest benefit is in its bonding strength to leather and the fact that it goes on white but dries completely clear. The leather allows for some time to work with it (2-3 minutes) yet dries fully in only 5-10 minutes allowing you to move on to the next steps in your project
The glue has a nice balance of drying strong, yet is pliable and able to move/flex with your leather.
