It is a runner of clear parts which can be used on plastic models detail-up works. Please use glue that is designed for plastic modes and/or clear parts for attaching. This product is a nice item for decorating or modifying those character models that you can find in market, and a great material for making "full-scratch" models (original model that is built from various material instead of a designed model kit). [Caution] Due to production reasons, there may be some unavoidable differences between the size of each part. Besides, there may be air bubbles in the clear parts. We appreciate your kind understanding. 【スペック】 Size: Approx. 75 x 65mm (in a runner form) Material: PS
