Our FF Trainer Kit has EVERYTHING you need to get inside. The cumplete KIT includes one slightly smaller hand and one larger one when you're ready. Sculpted with a smooth simplified hand shape, you can train without the worry of knuckles or nails. Made of pleasantly flexy PVC, they bend and move with you. Our included Vac-U-Lock suction base keeps 'em locked to ANY smooth surface so you can focus on opening up. We’ve packed this KIT with essentials: Slick ‘em up with FT Cum. Keep ‘em clean and fresh with FT Mean Clean, and Refresh Powder.
