Children's Groove Pen Control Calligraphy Practice Books with Refills

This children's groove pen control training set is built around four workbooks and a choice of refill quantities. The books cover numbers, addition and subtraction, drawing and letters, giving a child several areas of early writing and tracing practice within one set. Each book is made from white cardboard and measures 17.5cm in length, so it can be used on a table or desk at home, in a classroom or during quiet practice sessions. The set is supplied in an OPP bag and is available as 4 books plus 5 refills, 4 books plus 8 refills, or 4 books plus 10 refills. It sits within a calligraphy practice board series and is suited to children's pen control exercises. The source information also lists gift-giving suitability for occasions such as Full Moon and Children's Day, and for recipients including children, classmates, teachers, younger generation and elder generation.
Features and Construction

The set is designed around groove-based practice, with four workbooks covering different beginner skills. White cardboard is the stated material, and the 17.5cm length is the only measurement provided. The refill count changes by specification, so buyers can choose the quantity that matches their expected practice needs.
Material and Build
The books are made from white cardboard. In practical terms, this gives the pages a card-based structure for groove tracing and pen control exercises. The source information does not state page thickness, surface coating, binding type or ink compatibility, so those details should be confirmed separately if they are important to your purchase. The set is supplied in an OPP bag, which keeps the books and refills together before use and between practice sessions.
Size and Practical Fit
Each book measures 17.5cm in length. That is the only dimension given in the source information, so no width, height, page count or individual page size can be confirmed. The 17.5cm length makes the books a compact format for desk-based tracing and writing practice. They can be stored in the supplied OPP bag, which also helps keep the set together when travelling to a lesson or moving between rooms at home.
Uses and Placement

This set is intended for children's groove pen control training and calligraphy practice. The four books cover numbers, addition and subtraction, drawing and letters, so the set can be used across several early learning activities rather than a single subject. The refills allow practice to continue, with three refill options available.
Event or Professional Use
The source information lists gift-giving occasions including Full Moon and Children's Day. It also lists suitable gift-giving relationships such as younger generation, elder generation, children, classmates and teachers. This makes the set suitable as a practical gift for a child starting handwriting practice, or as a classroom or tutoring resource where repeated tracing exercises are useful. The OPP bag keeps the set presentable for giving and simple to store afterwards.
Everyday Home Use
At home, the books can be used for short, focused practice sessions covering number formation, addition and subtraction, drawing and letters. The groove design supports pen control practice, while the 17.5cm length keeps each book manageable on a table or desk. Because the set includes four books and refills, it can be used across multiple sessions. The source information does not specify age suitability, so adult guidance is advisable when choosing the right book for a child's current level.
Benefits and Buying Value

The main value of this set comes from combining four workbooks with refills in one purchase. It covers several practice areas and offers three refill quantities, so buyers can match the set to their expected frequency of use. The white cardboard construction and 17.5cm length are the stated physical details.
Reuse and Low Maintenance
Refills allow the practice books to be used again after the original refill is finished, provided the correct refill option is selected. The source information does not state ink type, drying time, refill lifespan or whether the pages are wipe-clean, so no cleaning or reuse method beyond refilling can be confirmed. Keeping the set in the supplied OPP bag helps protect the white cardboard books from dust and moisture during storage. Store them flat and dry when not in use.
Why Choose This Product
Choose this set if you want children's groove pen control practice across numbers, addition and subtraction, drawing and letters in one package. The four-book format and refill choices make it straightforward to match the set to home, classroom or gift use. It is made from white cardboard, measures 17.5cm in length, and is supplied in an OPP bag. No price, page count, ink colour, age rating or performance claims are stated in the source information, so the buying decision should rest on the confirmed book subjects, refill quantity and physical format.
