Jurusu,
All good questions!
The
Bow Hold Buddies™ accessory is indeed universal-fit, and works from 3 year hands to adult hands -- except for those husky men with double-wide thumbs that are too wide to fit into the accessory thumb hood [although they can still place their thumbs on the bottom, Mark O'Connor-style.]
Within the next year I hope to be able to offer the accessory in colors perhaps more appealing to adults:
Concert Black and
Frosty Clear.
However,
www.Things4Strings.com is just days away from being updated to offer the
Hold Fish™ pinky support as a separate item.
The
Hold Fish™ accessory will be offered in
Concert Black, Frosty Clear, Sunny Yellow, Sparkly Pink and
Bright Blue.
Also to be offered on the updated website will be a line of discounted
Studio Kits, sturdy storage cases of 12-18 durable, re-usable accessories at over 20% savings.
This will be the best way for studio teachers to help their students for years to come.
The accessory is safe for bows. Made of slightly elastic silcone rubber, it will stretch to accommodate the various diameters of bow shafts and wrappings.
There are many makes and styles of cases, but I have yet to find one that cannot absolutely safely store and transport a bow with the accessory installed -- but sometimes one has to be a bit creative.
If the case has a choice of an upper and lower storage spot, always try the lower one -- so when the case is closed the accessory will be on the side of the violin that does NOT have the chin rest on it. Always close with extra care the first time, to make sure there is room -- which there usually is, as the accessory is not much thicker than most chin rests.
If the accessory interferes with whatever device the case has to to hold the bow in place, then just lay the bow on the belly of the instrument, or on the violin cloth -- the accessory will then essentially become a rubber bumper, and neither scratch the violin nor allow bow to jangle around too much in the case.
If there really isn't enough room at all for the accessorized end of the bow to fit between the inside of the case and the lower belly of the violin when the case is closed [and I have seen this to be the case in some hard-sided cases], then a solution I used is to just lay the bow on the violin in the case BUT with the accessorized end nestling into the scroll storage area, again bypassing the case's standard bow storage features altogether. In the smallest fractional cases sometimes the Hold Fish™ accessory needs to be slipped off prior to storing the bow this way.
As always,
Best Wishes,
