Manual torch
Eco friendly manual torch is amazing new product that can be used without batteries. Twisting is only what you need to do to change mechanical energy into electrical energy, therefore, you can charge for the digital products without external power. Manual torch is environmentally good choice for you as promotional gift. It's affordable, charge timely and environmentally positive. There is plenty of room for your imprinted message, while production cost is inexpensive and it is used conveniently.
Any logos or images would be available to be imprinted on the manual torch, which is the best way to convey a new marketing concept and enhance the brand image of your company. Manual torch is the perfect low cost budget gift to get your green message noticed. I think it's also good educational tool for students to learn physical knowledge.
