Castle's Farrier's Choice Pack-Seal is an all-in-one, clear, fast-curing urethane-based adhesive designed to cushion the hoof, while offering full sole protection and support. It features a 30-second set-up time and a free mixing tip with the purchase of each cartridge. The larger cartridge size (210 ml) provides more coverage with each tube and is designed to save time and improve the application process. Benefits include a twist-off cap which allows cartridge to be sealed between uses, the cap and tip only fit one way into cartridge, and the cartridge fully locks into the applicator gun from the side before dispensing begins.
