We purchased 250 one-inch wheels with 1/4 inch axle holes, for a new project in the Edgewood Retirement Community (North Andover, MA) Wood Shop making toys for needy kids in our neighboring city of Lawrence. Yours is the third brand of wheels we have tried and love it that yours reallly are 1/4 inch axle holes. getting the wheels a much easier job. This year we will donate 40 toys. Next year shooting for 100. Ed Martin, Wood Shop Chairman
