Ok so it's not an emergency but I need a quick response. I've got homemade candles with various colors and scents (oil) made with soy mixed with regular pliable wax. (not sure which kind?) I've also got regular candles, some unscented and white from Walmart. Is it safe to use these, and will they leave burns or marks? And on the pain scale, what is typical for wax play? 10 being I just got stabbed in the gut, 5 being a lashed with a thin whip and 1 being nothing?
