The Globester™ is great for training wide and slopey grips and it really works your finger strength on wide pinches.
The Master is cut on a CNC router and each Globester is poured by hand in Sacramento California.
The 4 inch Globester and The Chunkster™ are both suitable for martial artists who want to develop grip strength as part of their training regiment.
Thanks for your interest in The Gripster! We are working hard to upscale our production but until we do we will be making each Gripster by hand. Since The Gripster is handmade in our workshop here in the San Fransisco Bay Area they are sometimes small defects such as bubbles or spots. Each Gripster is thoroughly tested for quality and we will not send you a below quality product. However, please note that they are handmade and therefore may sometimes contain tiny bubbles.
