Really big and strong suitcase 36X 57 X 87 cm. Plastic hard side case reinforced with aluminum metal strips (the red/orange metal). GripMaster brand. Suitable for use with equipment, not just clothes. All joints in which the two halves of the suitcase meet are metal and they overlap for security. There are no zippers. The locks are metal. The reason the price is so low is that you just have to get a locksmith to produce new keys for both locks because I lost the keys. This is the best suitcase I have ever encountered in the world. I bought in Japan. Easier to reach me on Whatsapp or email.
