The Oasis® OH-22 Grip-Strip™ is formulated from high-quality, textured, neoprene rubber. Precisely designed with slip resistant anti-skid ridges, it creates a secure grip for your guitar whenever it’s resting on your leg. You don’t have to worry about your guitar slipping and sliding around while you’re playing anymore. Grip-Strip™ works with both steel string and classical guitars, and it won’t harm the French polish finish on classical guitars. However, we do not recommend this product for new guitars where the finish has not yet settled in.
