GJP 250’s (2.5mm) are are for those who find the Gypsy Jazz Pick 3.5mm a bit too thick. The pick has the same dimensions as the standard GJP but comes in the lighter gauge of 2.5mm. However they give you the same great tone.The material used sounds very close to tortoise but lasts much longer. It has a nice bevelled and curved tip, so it makes a difference if you’re right or left handed. Both sides have grooves to grip. Please contact me if you require left handed picks. Condition is New unopened. Dispatched with Royal Mail 2nd Class Letter.
