You just never known when you might need to trim a piece of hanging thread or cut some paper or tape to size. Baumgarten's handy trimmers can be carried anywhere in your purse, backpack or briefcase. The translucent top locks into place for safety, so nothing gets cut unless you want it to. The handle is comfortable and easy to grip and ensures that you won't get your finger in the way while trimming. Please note: Current stock is all white with purple accents.
