Description of Change: In order to improve product delivery time and more eco-friendly. we will replace sponge with a relatively eco-friendly bubble wrap. It will take us at least one year to complete the switch. During this time, you may be exposed to both sponge and bubble wrap packed products. Reason: Part status change.Sponge is not environmental product. It produces environmental pollution and difficult to recycle. It is highly flammable and can cause deadly toxic gases when burning. At the same time, sponges are getting harder to buy due to the government's annual environmental inspections. Sometimes seriously affected our supply. So we will change to bubble wrap to avoid late delivery. The action is executed following a strict procedure, which guarantees no negative influence on quality, ability to supply and form/fit/function of the concerned products. All test was finished which guarantees the performance.
