Some one just wrote about paint sticks, emery paper and double
sided tape. I have been using the emery wands that can be
purched at K-mart for $1.17. They measure 3/4 x 7 inches. with
two different emery surfaces on both sides. These are found in
the ladies makeup dept. Used for shaping nails. I’ve used them
for about 5 years. and work well for pre polishing rings etc.
