Used but in very good condition. A dial caliper was used to measure the holes. Thumb hole measures .883” diameter. There are glued-in silicone inserts in the 2nd and 3rd finger holes but they can probably be removed. The major diameters are 2nd finger=.724” and 3rd finger=.640”. The holes will be larger with the silicone inserts removed. Distance from edge of thumb hole to edge of 2nd finger hole = 4-1/8”. Thumb to 3rd finger edge = 4-5/8”. Don’t know what the extra hole is from and the yellow and white spots may be weights underneath. Sold AS-IS. From a non-smoking house.
