The strongest jaw harp connector available. Very stable connection of the jaw harps thanks to the profile design. It can also be used with 4mm thick frame (e.g. Classic, Kancellar, Rococo, Aztec Mini) and 5mm thick frame (e.g. Black Fire, Balance Big, Baykal) jaw harps as well. It has a very tiny size, so it is very comfortable to use. Made of galvanized and stainless steel. No slipping of the instruments during playing. Connect two or more jaw harps for varied melodic playing. Recommended primarily for experienced players.
