Collar layliga caadiga ah waa qaybta iskutallaabta wareeg ah, xaruntu waxay leedahay dalool biyo ah, dhumucdiisuna waxay tahay derbiga waa ka weyn yahay, biibiile ka yar yahay, miisaanka ee dhererka unit kasta waa ka weyn yahay size ee tuubada dalool ku dhow 4- 5 jeer .The Most of Collar waa dunta si toos ah uga shaqaynaysa jidhka biibiile , laakiin qaar iyaga ka mid ah ayaa sidoo kale isticmaala isku-dhafka la beddelay.
Collar-daloolintu waa nooc ka mid ah qalabka lagu qodayo batroolka. Grooves Spiral waxay awood u siinaysaa dhoobada inay si xor ah ugu qulqulaan hareeraha qoob ka ciyaarka si ay u isticmaalaan cadaadiska dheelitirka si looga hortago samaynta xannibaadda si si wax ku ool ah looga hortago cadaadiska kala duwan. Meesha xiriirka ee ka soo horjeeda derbiga ceelka waa la gooyn karaa si si wax ku ool ah loo yareeyo suurtagalnimada samaynta xannibaad cadaadis kala duwan.
