Thank you for viewing! This is a set of 29 spring clasps from Hobbyra Hobbyre. + Includes 2 bonus mini spring clasps. Approximately 8.6cm spring clasps, 3 pieces per set x 10 bags * One piece has been used, so it's a set of 29 pieces. I purchased these and stored them, but I'm selling them because I no longer plan to use them. Retail price is ¥440 x 10 bags = ¥4,400. Although they are unused, they have been stored at home, so please refrain from purchasing if you are looking for a perfect item. Immediate purchase is OK. No price reduction.
