HANDMADE - Drawer Refresh Liners (Patent Pending) Pouch is made of Cotton/Canvas, inside Pads are infused with baking soda to help my t-shirts in the bottom of the drawer to smell fresher and I added a touch of essential oil “Citrus Lavender”.  One of my fav essential oils. 

The longer you leave these in the drawer, the more odors they absorb. When I left it in overnight, I really didn't notice a difference, but after a few days I started noticing a difference. And after 2 weeks, there was a big difference.

Could even hang them in your closet.

This is the info regarding baking soda I found online because I wasn't sure how long baking soda absorbed odors, "In a room, closet, or drawer baking soda can absorb odors for up to a year. Moisture and humidity can shorten the lifespan of baking soda's odor-absorbing properties."

Just put them on the bottom of your dresser drawers for your clothes to start smelling fresher.
