The Squid Industries Second Generation Mako Bottle Opener released in June 2019 adds performance and utility to the original design. By popular demand, we've redesigned the shark mouth to now function as a bottle opener. If you're looking for a competitive flipper that has a public friendly vibe, then the second generation Mako Bottle Opener is the trainer for you.

Each and every trainer is hand assembled and tested by to ensure that each unit is an exceptional flipper. Every trainer from Squid Industries comes thread locked however, extended flipping and use can cause the thread locker to break down over time so please be sure to maintain your trainer. Each trainer also comes with a box and sticker (artwork by @Spasmfingers).
