All of Funk Trunk products need your love and care While all items are made from eco-friendly sustainable wood, it is best not to expose them under extreme conditions and/or force. Use & Care Instructions: For hand wash only. Wipe clean with a damp cloth, use mild soap and water, then thoroughly clean with dry towel.  Make sure that the product is dry before storing it in a dry well-ventilated area away from extreme hot/cold temperature. To prolong its life, oil the wood portion of the product with vegetable or olive oil. To maintain appearance of the wood, rub it occasionally with food-grade mineral oil. Do NOT submerge in water or place in a dishwasher. Do NOT expose to extreme heat. Additional cleaning tips: For Bambler 2.0, make sure that you also clean the silicon part of its lid. For Bambucup, its lid can be cleaned by gently removing the lid's slider. Use a brush to clean. For Funkutlery, it should be cleaned and dried before storage.  For Bamboo Lunch box, do not put inside a microwave. If the storage area is experiencing high humidity, mold can appear. You can remove the mold easily by cleaning the item with water mixed with vinegar. Gently brush them. Have it sundried before storage.
