Purchased on Amazon in January 2024. This product is only two bottles out of a set of three sold on Amazon (accessories for only two bottles are included). It is new and unused. It will be shipped via Yu-Packet Plus. The following is a quote from the Amazon sales page: 【Satisfying Transparency】Even when embedding materials like dried flowers or insects, they are clearly visible. The smooth viscosity makes it easy to pour resin into the fine details of molds, and air bubbles are easily removed. It mixes well with colorants, resulting in beautiful colors. If you want to create your own colors, you can easily mix in colorants. 【High Quality and Safety】Made with VOC-free, non-toxic, and harmless materials. It doesn't have a strong odor and is environmentally friendly, so you can use it with peace of mind. It's a smooth type, so it doesn't leave a sticky residue, and there's no shrinkage or distortion, making it easy for beginners to use. 【Rapid Curing】Compared to epoxy resin, the curing time is shorter, hardening in about 2 minutes under UV light. It can also be cured in sunlight, taking no more than 5 minutes. You can enjoy a beautiful finish in a short amount of time. The nozzle design helps to pour the liquid into the mold. Note: Be careful not to add too much colorant, as this can prevent the UV light from reaching the resin and cause incomplete curing. 【Wide Range of Uses】The large 300g capacity offers good value. It's perfect as a gift for family and friends who are interested in UV resin crafts. It can be used for earrings, hair ties, necklaces, keychains, smartphone cases, and more. In this way, you can easily create original stationery and accessories with resin, in addition to accessories.
