I have a catalog from Woodworker's Supply in US, (505) 821-0574. They have 4 different sizes of screw extractors - 1/4" x 2, 3/8 x 2, 3/8 x 4-1/2 and 1/2 x 4-1/2. The two smaller ones sell for less than 15 dollars. They ship to foreign countries. Hope this helps. Tom -- Thomas A. Cole, RPT Santa Cruz, California
