The easy way to trim your glider’s nails is with the combination of the Wodent Wheel and the Wodent Wheel Nail Trimmer. This extra running track has a liner in it of emory board material in order to trim the nails of your glider as it has fun running in the wheel. It is not to be left in the wheel all of the time, but is meant to be put in the wheel for 2-3 days whenever your gliders need to have their nails trimmed. This wheel is great fun for the glider and a real work saver for the owner. Complete instructions included.
